Description

Technical Field

[0001] This invention relates to an analytical apparatus, a method for protecting the analytical apparatus, a protective component, and an analytical system. Background Technology

[0002] Previously, in order to analyze exhaust gases emitted from vehicles while they are in motion, portable analytical devices were developed, either by mounting the analytical device on the vehicle or by moving the analytical device to a desired location in the laboratory for analysis.

[0003] Such an analytical device, as shown in Patent Document 1, includes: a housing, generally rectangular in shape, with one or more connection terminals on the front; and handles provided on the front and back of the housing for the operator to grip during transport. The handle on the front of the housing is used not only by the operator during transport but also, for example, when securing the analytical device with a safety belt. Thus, the analytical device can be transported and secured even when performing analysis while the vehicle is in motion.

[0004] Here, in the aforementioned analytical apparatus, the handle protrudes vertically from the front of the housing. In this case, in the front view, the corners of the housing formed along the vertical direction are covered by the handle. Furthermore, the handle located on the rear also covers the corners in the rear view.

[0005] However, in the aforementioned analytical device, the handle does not cover the corners in the right or left view, thus failing to protect them. As a result, there is a risk that the analytical device may be damaged by its surroundings when the operator moves it. Prior art literature

[0006] Patent Document 1: Japanese Patent Publication No. 2015-210255 Summary of the Invention

[0007] In view of the above-mentioned problems, the main objective of the present invention is to prevent the analytical device from being damaged by its surroundings when it is moved.

[0008] That is, the analytical device of the present invention is a portable analytical device, characterized in that it includes: a cuboid-shaped analytical device body; and a protective member for protecting a corner portion, the corner portion being formed by the side surfaces of the analytical device body adjacent to each other in the vertical direction, the protective member having a through portion between itself and the corner portion for fixing the analytical device body to a predetermined location, the protective member being separately disposed from the corner portion such that it covers the corner portion in the side view of each side surface forming the corner portion.

[0009] With this structure, since protective members cover the corners in the side views of each side forming the corners, the main body of the analyzer can be prevented from directly colliding with its surroundings when the operator moves the analyzer. As a result, damage to the main body of the analyzer and the equipment housed within it can be prevented. Furthermore, since the protective member forms a through portion between itself and the corner for the fixing member to pass through, the analysis device can be fixed at a specified location by passing the fixing member through the through portion.

[0010] Preferably, the protective components are independently disposed at two or more of the corners.

[0011] With this structure, when a protective component is damaged, unlike the case where protective components protecting each corner are formed as a single unit, only the damaged protective component needs to be replaced, and there is no need to replace other protective components.

[0012] Preferably, there are two or more through portions along the vertical direction.

[0013] With this structure, when the fixing component is, for example, a belt, the operator can appropriately change the through-section through which the belt passes, depending on the length of the belt and / or the fixing position of the main body of the analytical device. Specifically, when the fixing position is high, the operator passes the belt through the upper through-section of one of two or more through-sections formed in the vertical direction. Furthermore, when the fixing position is low, the operator passes the belt through the lower through-section of one of two or more through-sections formed in the vertical direction. In this way, the through-sections can be used separately according to the height of the fixing position, thus allowing the main body of the analytical device to be fixed to various fixing positions.

[0014] As a specific numerical range that allows a fixing member, such as a belt, to pass through and prevent the operator's fingers from being caught between the corner and the protective member, examples can be given where the distance between the corner and the protective member is more than 0.1 mm and less than 20 mm.

[0015] Preferably, the analysis device further includes a limiting part for restricting the movement of the fixed member in the vertical direction.

[0016] This structure prevents the fixing components from falling downwards and allows them to be more stably fixed to the analysis device.

[0017] Preferably, the limiting part is disposed between the corner and the protective member in a vertical direction, and the distance between the limiting part and the corner is less than the distance between the protective member and the corner.

[0018] With this structure, the distance between the limiting part and the corner is smaller than the distance between the protective member and the corner, so the operator's fingers can be prevented from being pinched in the part where the limiting part is provided.

[0019] Preferably, in a cross-sectional view perpendicular to the vertical direction, the limiting portion is formed in a shape that gradually narrows from the protective member toward the corner.

[0020] With this structure, in the cross-sectional view, the limiting part has a shape that gradually narrows from the protective member toward the corner, so the operator can easily bring their fingers close to the limiting part from the outside, but prevents the operator's fingers from being pinched when they are close to the limiting part. Furthermore, in the cross-sectional view, since the limiting part has a shape that gradually narrows from the protective member toward the corner, the limiting part is not visible from the outside, thereby improving the aesthetics and design of the analysis device.

[0021] Specifically, in a cross-sectional view perpendicular to the vertical direction, the protective member is rectangular and the limiting part is trapezoidal.

[0022] Preferably, the side panel constituting the side of the main body of the analytical device is detachable from the main body of the analytical device and also has a handle that is mounted on the side panel for the operator to hold.

[0023] With this structure, for example, when it is necessary to clean the inside of the analysis device or remove the side of the main body of the analysis device, the side panel can be easily installed or removed by holding the handle.

[0024] A method for protecting a portable analytical device, the analytical device comprising: a cuboid-shaped analytical device body; and a protective member for protecting corner portions formed by adjacent sides of the analytical device body in a vertical direction, the method being characterized in that the protective member is disposed separately from the corner portion such that it covers the corner portion in a side view of each side portion forming the corner portion, and the analytical device body is fixed to the predetermined location by passing a fixing member for fixing the analytical device body to the predetermined location through a through portion, the through portion being formed between the corner portion and the protective member. Furthermore, a protective member is provided on a portable analytical device having a cuboid-shaped analytical device body. The protective member protects a corner portion formed by the side surfaces of the analytical device body adjacent to each other in the vertical direction. The protective member is characterized in that it has a through portion for fixing the analytical device body to a predetermined location. The protective member is separated from the corner portion in such a way that it covers the corner portion in the side view of each side surface forming the corner portion.

[0025] With this structure, the same effect as the analytical device described above can be achieved.

[0026] An analysis system analyzes exhaust gas from a test object, characterized by comprising: a sampling unit for sampling the exhaust gas from the test object; an analysis device for analyzing the exhaust gas sampled by the sampling unit; and an information processing device for receiving the analysis results from the analysis device, storing the analysis results, or processing the analysis results. Additionally, the analysis system may further include a test object testing device for testing the test object. Furthermore, the analysis device can analyze the exhaust gas sampled by the sampling unit while mounted on the test object.

[0027] With this structure, the same effect as the analytical device described above can be achieved.

[0028] According to the present invention, damage to the analytical device due to contact with surrounding objects can be prevented when the analytical device is moved. Attached Figure Description

[0030] The analysis apparatus according to one embodiment of the present invention will now be described with reference to the accompanying drawings. Furthermore, for ease of understanding, all the drawings shown below contain appropriate omissions or exaggerated schematic representations. The same reference numerals are used for the same structural components, and descriptions are appropriately omitted.

[0031] (Device structure) The analytical apparatus 100 of this embodiment can be moved by an operator. Specifically, the analytical apparatus 100 is moved to the usage position by the operator and fixed in a designated position by a designated fixing member during analysis.

[0032] The analytical apparatus 100 analyzes the sample gas. Here, sample gas refers to exhaust gas, atmospheric gas, and / or process gas emitted from the analyte. The analyte refers to mobile bodies such as vehicles (including, for example, hydrogen cars, ICEVs, fuel cell vehicles, or hybrid vehicles), ships, railways, or aircraft; combustion devices (including, for example, external combustion engines, industrial furnaces, incinerators, turbines, or power plants); and / or chemical equipment (including petrochemical, coal chemical, natural gas chemical, petroleum refining, methanation, and / or gasification furnaces).

[0033] Furthermore, the analytical objects of the analytical apparatus 100 in this embodiment are the component concentrations in the sample gas, the vehicle's acceleration, the flow rate of the sample gas, the number of particulate matter in the sample gas, and the mass of particulate matter in the sample gas, such as the concentrations of specified components contained in exhaust gases such as air, process gases, and / or engine exhaust or flue gas. Additionally, the analytical objects of the analytical apparatus 100 may include, for example, carbon monoxide, carbon dioxide, nitrogen oxides, methane, formaldehyde, total hydrocarbons (THC), ammonia, hydrogen, oxygen, and / or nitrous oxide, but are not limited to these.

[0034] The analytical apparatus 100 in this embodiment is a vehicle-mounted device for analyzing sample gases emitted from a vehicle while the vehicle is in motion, a stationary device installed in a desired location such as a laboratory, and / or a portable device that can be moved to a desired location. The vehicle-mounted type includes those installed in the vehicle seat, those installed in the vehicle trunk, or those installed on a vehicle rack mounted on a vehicle's rear-mounted component. Furthermore, both the stationary and portable analytical apparatus 100 can be used indoors and outdoors.

[0035] Specifically, such as Figure 1 As shown, the analysis apparatus 100 of this embodiment includes: an analysis apparatus body 1 in a generally rectangular parallelepiped shape; a protective member 2 protecting the analysis apparatus body 1; a limiting part 3 restricting the vertical movement of a fixing member F, such as a strap; and a handle part 4 mounted on the side of the analysis apparatus body 1 and held by the operator. Each part will be described below. Furthermore, the generally rectangular parallelepiped shape described here includes shapes resembling a rectangular parallelepiped with a missing corner, shapes with chamfered corners, and shapes with slightly uneven surfaces forming on the surfaces constituting the rectangular parallelepiped.

[0036] The main body of the analytical apparatus 1 analyzes the sample gas sampled using a sampling section (not shown). The main body of the analytical apparatus 1 includes an analyzer (not shown) for analyzing the sample gas and a side panel that forms the side of the main body of the analytical apparatus 1.

[0037] The analyzer can analyze, for example, the concentration of the sample gas, the number of microparticles contained in the sample gas, the volume of microparticles, the flow rate of the sample gas, the temperature of the sample gas, the humidity of the sample gas, the viscosity of the sample gas, and / or the flow rate of the sample gas. When determining the concentration of the sample gas, the analyzer can employ infrared absorption spectroscopy methods such as non-dispersive infrared absorption (NDIR), Fourier transform infrared spectroscopy (FTIR), and / or infrared laser absorption modulation, as well as flame ionization detection and / or other methods. When analyzing the number of particles, the analyzer can employ a condensed particle counter (CPC).

[0038] The side panel is detachable from the main body 1 of the analytical apparatus. With the side of the main body 1 containing hoses or connecting pipes, or the connection terminal P that is electrically connected to each device, as the front side of the main body 1, the sides of the main body 1 in this embodiment include a front, a back, a right side, and a left side. Furthermore, the connection terminal P may be, for example, a sample gas inlet terminal for introducing sample gas into the interior of the main body 1, a power terminal connected to a power line from a power supply unit (not shown), an information device terminal such as a LAN interface for exchanging information and data with each device, and / or an adjustment gas inlet terminal for introducing calibration gas and / or purification gas.

[0039] The protective member 2 is formed into a generally flat plate shape along the vertical direction, and is used to protect the corner portion 11 formed by the sides of the analytical device body 1 that are adjacent to each other along the vertical direction. In this embodiment, the corner portion 11 refers to the portion formed between two adjacent sides of the analytical device body 1. More specifically, the corner portion 11 is the portion formed by cutting off the top edge formed by connecting two adjacent sides of the front, back, right, and left sides of the analytical device body 1 along the vertical direction. Alternatively, if the top edge is not cut off along the vertical direction, the corner portion 11 may be the top edge itself.

[0040] The protective components 2 are independently installed at two or more corners 11. In this embodiment, as shown... Figure 1 As shown, each of the four corner portions 11 is independently provided with a protective member 2. In this embodiment, the four protective members 2 are of the same shape, but they can also be different shapes from each other.

[0041] Here, as Figure 2 and Figure 3As shown, in the various side views forming the corner 11, namely the front view, rear view, and side view, the protective member 2 is separately provided from the corner 11 in a manner that covers the corner 11. Specifically, observing the area formed by virtually extending each side of the corner 11 toward the protective member 2, the protective member 2 is separately provided from the corner 11 in a manner that covers the corner 11.

[0042] Here, in the front and side views, the protective member 2 is separated from the corner 11 by covering the front end portion 11a of the corner 11. Here, the front end portion 11a of the corner 11 refers to the surface or edge on the front end side of the corner 11. More specifically... Figure 4 As shown, the front end 11a of the corner 11 protrudes outward toward the outer side of the main body 1 of the analysis device and is the surface or edge closest to the protective member 2.

[0043] In this embodiment, the protective member 2 has an opposing surface 2a opposite to the front end portion 11a. Furthermore, as... Figure 4 As shown, the length of the short side of the opposing surface 2a of the protective member 2 is greater than the width of the front end 11a.

[0044] The protective member 2 is disposed on the analytical apparatus 100 via a mounting portion installed on the upper and / or lower surface of the analytical apparatus 100. Specifically, as follows... Figure 2 and Figure 3 As shown, the protective member 2 is connected to the upper mounting member S1 mounted on the upper surface of the analyzer body 1 and the lower mounting member S2 mounted on the lower surface of the analyzer body 1, and is separately disposed from the corner portion 11. Furthermore, in this embodiment, the protective member 2 is detachable from the upper mounting member S1 and the lower mounting member S2, and is a separate component from them; however, the protective member 2, the upper mounting member S1, and the lower mounting member S2 can also be formed as a single, integrated component.

[0045] In addition, such as Figure 1 and Figure 5 As shown, the protective member 2 has a through portion 2b between it and the corner portion 11. The through portion 2b is for the fixing member F, which is used to fix the main body 1 of the analysis device at a specified position, to pass through. Figure 5 This is a partially enlarged view of the portion through which the fixing member F passes, taken in a cross-sectional view cut along the vertical direction through the center of the width of the protective member 2. In this embodiment, the through portion 2b is a space formed between the front end portion 11a and the opposing surface 2a of the protective member 2 by separating the protective member 2 from the corner portion 11. Furthermore, the distance between the corner portion 11 and the protective member 2 should be at least 30 mm or less. Preferably, the distance between the corner portion 11 and the protective member 2 is 0.1 mm or more and 20 mm or less. This allows a fixing member F, such as a strap, to pass through while preventing the operator's fingers from being caught between the corner portion 11 and the protective member 2.

[0046] Here, for a single protective member 2, two or more through portions 2b are formed in the vertical direction. In this embodiment, for a single protective member 2, two through portions 2b are formed in the vertical direction. More specifically, the two through portions 2b are spaces formed above and below the limiting portion 3, which will be described later, by providing the limiting portion 3 in the central part of the protective member 2.

[0047] The limiting part 3 is columnar, extending vertically, and is disposed between the corner part 11 and the protective member 2. Specifically, as follows... Figure 5 and Figure 6 As shown, the upper and lower surfaces of the limiting part 3 are configured such that the distance between the upper surface of the limiting part 3 and the upper end of the protective member 2, and the distance between the lower surface of the limiting part 3 and the lower end of the protective member 2, are equal to or slightly greater than the width of the fixing member F. As a result, as... Figure 5 and Figure 6 As shown, the upper and lower surfaces of the limiting part 3 function as limiting parts 3 to restrict the vertical movement of the fixing member F. Furthermore, in this embodiment, the limiting part 3 and the protective member 2 are different components, but the protective member 2 and the limiting part 3 may also be formed as a single, integral component.

[0048] In addition, such as Figure 4 and Figure 5 As shown, the distance between the limiting part 3 and the corner part 11 is smaller than the distance between the protective member 2 and the corner part 11. Specifically, as shown... Figure 4 and Figure 5 As shown, the distance between the opposing surface 3a and the front end portion 11a of the limiting portion 3, which is opposite to the corner portion 11, is smaller than the distance between the opposing surface 2a and the front end portion 11a of the protective member 2. Through this structure, the limiting portion 3 also functions as a hand-pinching prevention part, preventing the operator's fingers from being pinched when the operator grips the protective member 2 and the limiting portion 3.

[0049] Moreover, such as Figure 4 As shown, in a cross-sectional view perpendicular to the vertical direction, the limiting portion 3 is formed into a shape that gradually narrows from the protective member 2 toward the corner 11. Specifically, as... Figure 4 As shown, in a cross-sectional view perpendicular to the vertical direction, the protective member 2 is rectangular and the limiting part 3 is trapezoidal. Hereinafter, in the set of parallel sides of the trapezoidal limiting part 3, the side closest to the corner 11 is designated as the upper base, the side separated from the corner 11 is designated as the lower base, and the other sides of the trapezoidal limiting part 3 are designated as the waist.

[0050] like Figure 4As shown, in a cross-sectional view perpendicular to the vertical direction, the upper and lower bases are parallel to the front end 11a of the corner 11, and the length of the upper base is less than the length of the lower base. Furthermore, in a cross-sectional view perpendicular to the vertical direction, it is preferable that the angle between the surface forming the waist and the side of the analyzer body 1 is 90 degrees or less; in this embodiment, the angle between the waist and the side of the analyzer body 1 can be 90 degrees. Additionally, the length of the lower base can be the same as or different from the length in the width direction of the protective member 2. Preferably, the length of the lower base is less than or equal to the length in the width direction of the protective member 2.

[0051] The handle 4 is roughly flat and is mounted on the side panel of the main body 1 of the analysis device. Figure 2 He Ru Figure 3 As shown, the handle 4 is mounted perpendicular to the length of the protective member 2 at the lower end of the side panel of the analyzer body 1. This allows the operator to grip the handle 4 to attach or detach the side panel. Alternatively, the handle 4 can be partially detached from the side panel, allowing the operator to grip it to move the analyzer body 1. Furthermore, the position of the handle 4 on the side panel is not limited to the lower end; it can be at the upper end or any position from the lower to the upper end of the side panel.

[0052] In addition, such as Figure 4 and Figure 7 As shown, the two ends of the handle portion 4 along its length direction can be bent along the corner portion 11, and the outer peripheral surfaces of the two ends of the handle portion 4 along its length direction are on the same plane as the outer peripheral surface of the protective member 2. Furthermore, in this embodiment, all four side panels of the analyzer body 1 are equipped with handle portions 4; however, it is sufficient to install handle portions 4 on at least two opposite side panels of the analyzer body 1, rather than on all four side panels. Here, if all four side panels are equipped with handle portions 4, multiple operators can move the heavier analyzer body 1. On the other hand, for a lighter analyzer body 1, handle portions 4 can be installed on two side panels.

[0053] (Effects of this implementation method) According to the analysis apparatus 100 in this embodiment, since the protective member 2 covers the corner 11 when viewed from each side forming the corner 11, the analysis apparatus body 1 can be prevented from directly colliding with its surroundings when the operator moves the analysis apparatus 100. As a result, damage to the analysis apparatus body 1 and the equipment housed within it can be prevented. Furthermore, since a through portion 2b for passing through the fixing member F is formed between the corner portion 11 and the protective member 2, the analysis device 100 can be fixed at a specified location by passing the fixing member F through the through portion 2b.

[0054] Furthermore, since protective components 2 are independently provided at two or more corners 11, when a protective component 2 is damaged, compared to the case where the protective components 2 protecting each corner 11 are integrally formed, only the damaged protective component 2 needs to be replaced, and there is no need to replace other protective components 2. In particular, in this embodiment, since each of the four corners 11 is provided with a protective member 2 independently, all four corners 11 can be protected. Compared with the case where the protective member 2 protecting each corner 11 is formed as one piece, the replacement of the protective member 2 is also easy.

[0055] Furthermore, two or more through sections 2b are formed along the vertical direction. Therefore, when the fixing member F is, for example, a belt, the operator can appropriately change the through section 2b through which the belt passes, according to the length of the belt.

[0056] In addition, since the analysis device 100 also has a limiting part 3 for limiting the movement of the fixing member F in the vertical direction, it can prevent the fixing member F from falling downward and can further stabilize the fixing member F in the analysis device 100.

[0057] Furthermore, since the distance between the limiting part 3 and the corner part 11 is smaller than the distance between the protective member 2 and the corner part 11, the operator's hand can be prevented from being pinched at the location where the limiting part 3 is provided.

[0058] Furthermore, in a cross-sectional view perpendicular to the vertical direction, the limiting part 3 is formed in a shape that gradually narrows from the protective member 2 toward the corner 11, so that the operator can easily approach the limiting part 3 from the outside, and prevents the operator from getting their hand pinched when their finger approaches the limiting part 3. Furthermore, in the cross-sectional view, the limiting part 3 is formed in a shape that gradually narrows from the protective member 2 toward the corner 11, so the limiting part 3 is not visible from the outside, thereby improving the aesthetics and design of the analysis device 100.

[0059] In addition, since the analyzer 100 also has a handle 4 that is held by the operator on the side panel that is installed on the side of the analyzer body 1, the side panel can be easily installed or removed by holding the handle 4 when it is necessary to remove the side panel, such as when cleaning the analyzer 100.

[0060] (Other implementation methods) Furthermore, the present invention is not limited to the embodiments described above.

[0061] In the above embodiment, the protective member 2 is generally flat, but the shape of the protective member 2 is not limited to this. The shape of the protective member 2 is only required to cover the front end 11a of the corner 11 when viewed from each side of the corner 11, and it can be other shapes such as cylindrical or hexagonal prism.

[0062] In the above embodiment, all four corner portions 11 are provided with protective members 2, but it is sufficient to provide protective members 2 at at least two corner portions 11. Furthermore, in the above embodiment, the protective members 2 are provided independently, but the protective members 2 can also be integrally formed to protect each corner portion 11.

[0063] In the above embodiment, two through portions 2b are formed along the vertical direction, but this is not a limitation. There may be one through portion 2b or more than three through portions 2b.

[0064] In the above embodiment, the protective member 2 has a through portion 2b between it and the corner portion 11. However, the protective member 2 can also have a through portion 2b by forming a through space in the protective member 2.

[0065] In the above embodiment, the distance between the corner 11 and the protective member 2 is 0.1 mm or more and 20 mm or less. However, as long as a fixing member F such as a belt can pass through and the operator's fingers can be prevented from being pinched between the corner 11 and the protective member 2, the distance between the corner 11 and the protective member 2 is not limited to the above-mentioned numerical range.

[0066] In the above embodiment, in a cross-sectional view perpendicular to the vertical direction, the limiting part 3 is trapezoidal, but it can be any shape that gradually narrows from the protective member 2 toward the corner 11. For example, in a cross-sectional view perpendicular to the vertical direction, the shape of the limiting part 3 can also be a semi-circle or other shapes.

[0067] In the above embodiment, the upper mounting member S1 and / or the lower mounting member S2 further include a positioning part, which positions the other analytical device when it is mounted on the upper or lower surface of the analytical device body 1. Specific examples of the positioning part include, for instance, uneven shapes formed on the surfaces of the upper mounting member S1 and / or the lower mounting member S2, and / or holes for inserting positioning pins into the upper mounting member S1 and / or the lower mounting member S2. Thus, when other analytical devices are mounted on the upper or lower surface of the analytical device body 1, the other analytical devices are positioned by the positioning part, preventing movement of the other analytical devices on the upper or lower surface of the analytical device body 1. Alternatively, all of the upper mounting members S1 and / or the lower mounting members S2 may have positioning parts, or only a portion of the upper mounting members S1 and / or the lower mounting members S2 may have positioning parts.

[0068] In the above embodiment, the analysis device 100 includes a limiting part 3 and a handle part 4, but it may also omit the limiting part 3 and the handle part 4. Even in this case, it is possible to prevent the analysis device 100 from being damaged by its surroundings when it moves.

[0069] As another embodiment of the above-described implementation, the analysis system 200 for analyzing exhaust gas from the test object V may include the analysis device 100. Specifically, as follows... Figure 8 As shown, the analysis system 200 may further include: a sampling unit 5 for sampling exhaust gas from the test object V; and an information processing unit 6 for receiving and processing the analysis results analyzed by the analysis device 100. Additionally, Figure 8 The text indicates that the tested object V is a vehicle, but the tested object V is not limited to vehicles.

[0070] Here, the sampling unit 5 may also include: an exhaust pipe connector 51 connected to the vehicle's exhaust pipe; a flow meter 52 for measuring the flow rate of the exhaust; and an exhaust inlet pipe 53 for introducing the exhaust from the exhaust pipe into the analysis device 100. The flow meter 52 measures all the exhaust discharged from the test object V. Alternatively, the flow meter 52 may be, for example, a pitot tube flow meter. The exhaust inlet pipe 53 introduces a portion of the exhaust discharged from the test object V into the analysis device 100. The information processing device 6 can determine the mass and / or volume of a specified component contained in the exhaust based on the exhaust concentration measured by the analysis device 100 and the exhaust flow rate measured by the flow meter 52.

[0071] exist Figure 8 In this configuration, the analytical apparatus 100 is placed on a mounting member B, which is separate from the test object V, and is fixed to the mounting member B by means of a fixing member F. Here, the mounting member B can also be, for example, a frame and / or a shelf. The fixing member F passes through the through-section 2b of the analytical apparatus 100 and is mounted on a support of the mounting member B, thereby fixing the analytical apparatus 100 to the mounting member B. Furthermore, according to... Figure 8 The information processing device 6 is also placed on the mounting member B, but the information processing device 6 may also not be placed on the mounting member B.

[0072] Furthermore, the analysis device 100 may also include a test subject testing device 7 for testing the test subject V. Figure 8 The test device 7 is a so-called chassis dynamometer equipped with a roller 71 for loading the test object V and a control device 72 for controlling the roller, but it is not limited to this. The test device 7 can also be other test devices such as an engine dynamometer or a drive system dynamometer.

[0073] Moreover, as Figure 9 As shown, in the analysis system 200, the analysis device 100 can also analyze the exhaust gas sampled by the sampling unit 5 while mounted on the test object V. In this case, the fixing member F passes through the through portion 2b and is installed on the test object V, thereby fixing the main body 1 of the analysis device to a predetermined position M inside the test object V. Figure 9The specified location M is the vehicle's trunk, and the analysis device 100 is fixed inside the trunk by means of a fixing member F, but it is not limited to this.
