Description

[Technical Field]

[0001] The present invention relates to an analytical device, a method for protecting an analytical device, a protective member, and an analytical system. [Background technology]

[0002] Portable analytical devices have been developed to enable analysis of exhaust gases emitted from a vehicle while the vehicle is running, or to enable the analytical device to be moved to a desired location in a laboratory for analysis.

[0003] As shown in Patent Document 1, for example, this type of analytical device includes a roughly rectangular parallelepiped housing with one or more connection terminals on the front, and handles on the front and back of the housing to be grasped by an operator when carrying the device. The handles on the front of the housing are configured to be used not only when the operator is carrying the device, but also to secure the analytical device with, for example, a seat belt. This makes the analytical device portable, while also allowing the analytical device to be secured when performing analysis while the vehicle is moving.

[0004] In the above-described analytical device, the handle is provided on the front surface of the housing, protruding perpendicularly to the front surface of the housing. In this case, the handle covers the corners of the housing formed along the vertical direction when viewed from the front. Similarly, the handle provided on the rear surface also covers the corners when viewed from the rear.

[0005] However, in the above-described analyzer, the handle does not cover the corners when viewed from the right or left side, so the handle cannot protect the corners. As a result, when an operator moves the analyzer, the analyzer may bump into something around it, which could result in damage to the analyzer. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-210255 Summary of the Invention [Problem to be solved by the invention]

[0007] The present invention has been made in view of the above problems, and its main object is to prevent the analyzer from colliding with its surroundings and being damaged when it is moved. [Means for solving the problem]

[0008] In other words, the analytical device of the present invention is a portable analytical device comprising a rectangular parallelepiped analytical device main body and a protective member that protects corners formed in the vertical direction by the side surfaces of adjacent analytical device main bodies, and the protective member forms a through portion between the corners for fixing the analytical device main body to a predetermined location, and is characterized in that it is arranged away from the corners so as to cover the corners when viewed from the side on each side that forms the corners.

[0009] With this configuration, the protective members cover the corners in a side view on each side surface that forms the corners, preventing the analyzer body from directly bumping into the surroundings when an operator moves the analyzer, thereby preventing damage to the analyzer body and the devices housed in the analyzer body. Furthermore, the protective member has a through-hole formed between the corner and the protective member for passing the fixing member therethrough, so that the analytical device can be fixed in place by passing the fixing member through the through-hole.

[0010] It is preferable that the protective members are provided independently at two or more of the corners.

[0011] With this configuration, if a protective member is damaged, it is only necessary to replace the damaged protective member, and there is no need to replace other protective members, compared to when the protective members that protect each corner are formed as a single unit.

[0012] It is preferable that two or more of the through-portions are formed along the vertical direction.

[0013] With this configuration, if the fixing member is, for example, a belt, the operator can change the threading portion through which the belt passes depending on the length of the belt and / or the fixing location where the analyzer main body is fixed. Specifically, if the fixing location is high, the operator passes the belt through the upper one of two or more threading portions formed along the vertical direction. On the other hand, if the fixing location is low, the operator passes the belt through the lower one of two or more threading portions formed along the vertical direction. This allows the operator to use different threading portions depending on the height of the fixing location, making it possible to fix the analyzer main body to a variety of fixing locations.

[0014] For example, a specific numerical range for allowing a fixed member such as a belt to pass through and preventing an operator's fingers from getting caught between the corner and the protective member is a distance of 0.1 mm or more and 20 mm or less between the corner and the protective member.

[0015] It is preferable that the analyzer further includes a restricting portion that restricts the fixing member from moving in the vertical direction.

[0016] With this configuration, the fixing member can be prevented from dropping downward, and the fixing member can fix the analysis device more stably.

[0017] The regulating portion is preferably provided between the corner and the protective member in the vertical direction, and the distance between the regulating portion and the corner is preferably smaller than the distance between the protective member and the corner.

[0018] With this configuration, the distance between the restricting portion and the corner is smaller than the distance between the protective member and the corner, thereby preventing the worker's fingers from getting caught in the area where the restricting portion is provided.

[0019] In a cross section perpendicular to the up-down direction, the restricting portion preferably has a shape that gradually narrows from the protective member toward the corner portion.

[0020] With this configuration, when viewed in cross section, the restricting portion has a shape that gradually narrows as it moves from the protective member toward the corner, making it easier for an operator to hook their fingers onto the restricting portion from the outside and preventing the operator's fingers from getting pinched when hooking their fingers onto the restricting portion. Furthermore, when viewed in cross section, the restricting portion has a shape that gradually narrows from the protective member toward the corner, making it possible to make the restricting portion invisible from the outside, thereby improving the aesthetics and design of the analytical device.

[0021] Specifically, in a cross section perpendicular to the up-down direction, the protection member has a rectangular shape, and the restriction portion has a trapezoidal shape.

[0022] The side panel that constitutes the side of the analyzer body is preferably configured to be detachable from the analyzer body, and further includes a handle that is attached to the side panel and can be gripped by an operator.

[0023] With this configuration, when it is necessary to remove the side panel of the analyzer body, for example to clean the inside of the analyzer, the side panel can be easily attached and detached by holding the handle.

[0024] A method for protecting a portable analyzer comprising a rectangular parallelepiped analyzer body and protective members for protecting corners formed in the vertical direction by the side surfaces of adjacent analyzer bodies, the method comprising providing the protective members away from the corners so as to cover the corners in a side view on each of the sides forming the corners, and fixing the analyzer body to a predetermined location by passing a fixing member for fixing the analyzer body to the predetermined location through a through-hole formed between the corners and the protective members. The present invention also provides a protective member that is provided on a portable analytical device having a rectangular parallelepiped analytical device main body, and that protects corners formed in the vertical direction by the side surfaces of adjacent analytical device main bodies, wherein the protective member forms a through portion for fixing the analytical device main body to a predetermined location, and is provided away from the corners so as to cover the corners when viewed from the side on each of the side surfaces that form the corners.

[0025] With this configuration, it is possible to obtain the same effects as those of the above-described analyzer.

[0026] An analysis system for analyzing exhaust gas from a test specimen includes a sampling unit that samples the exhaust gas from the test specimen, an analysis device that analyzes the exhaust gas sampled by the sampling unit, and an information processing device that receives analysis results analyzed by the analysis device and stores or processes the analysis results. The analysis system may further include a test specimen testing device that tests the test specimen. The analysis device may analyze the exhaust gas sampled by the sampling unit while mounted on the test specimen.

[0027] With this configuration, it is possible to obtain the same effects as those of the above-described analyzer. [Effects of the Invention]

[0028] According to the present invention, it is possible to prevent the analyzer from colliding with its surroundings and being damaged when it is moved. [Brief explanation of the drawings]

[0030] An analytical device according to one embodiment of the present invention will be described below with reference to the drawings. Note that in all of the drawings shown below, some parts may be omitted or exaggerated for clarity. Identical components are designated by the same reference numerals, and their description will be omitted where appropriate.

[0031] <Device configuration> The analysis device 100 of this embodiment is portable by an operator. Specifically, the analysis device 100 is carried by the operator to a location where it will be used, and is fixed in a predetermined location by a predetermined fixing member during analysis.

[0032] The analytical device 100 analyzes a sample gas. Here, the sample gas refers to a gas such as exhaust gas, atmospheric air, and / or process gas emitted from a test object. The test object referred to here may be a vehicle (here, a vehicle includes, for example, a hydrogen-powered vehicle, an internal combustion engine (ICEV), a fuel cell vehicle, or a hybrid vehicle), a ship, a train, or an airplane, a combustion engine (here, a combustion engine includes, for example, an external combustion engine, an industrial furnace, an incinerator, a turbine, or a power plant), and / or a chemical plant (here, a chemical plant includes, for example, a petrochemical, a coal chemical, a natural gas chemical, an oil refinery, a methanation and / or a gasifier), etc.

[0033] The analysis targets of the analysis device 100 of this embodiment include the concentration of a component in the sample gas, the acceleration of the vehicle, the flow rate of the sample gas, the number of particulate matter in the sample gas (particle number), the mass of particulate matter in the sample gas (particle mass), and the concentration of a predetermined component contained in, for example, the atmosphere, process gas, and / or exhaust gas such as engine exhaust gas or flue gas. Examples of components to be analyzed by the analysis device 100 include, but are not limited to, carbon monoxide, carbon dioxide, nitrogen oxides, methane, formaldehyde, total hydrocarbons (THC), ammonia, hydrogen, oxygen, and / or nitrous oxide.

[0034] The analytical device 100 in this embodiment may be an on-board type that analyzes sample gas emitted from a vehicle while the vehicle is running, a stationary type that is installed in a desired location such as a laboratory, and / or a portable type that can be transported to a desired location. The on-board type here includes those that are installed on a vehicle seat, a vehicle trunk, or a hitch carrier that is installed on a stand attached to a vehicle. The stationary type analytical device 100 and the portable type analytical device 100 can be used both indoors and outdoors.

[0035] Specifically, as shown in Fig. 1, the analyzer 100 of this embodiment comprises an analyzer main body 1 having a roughly rectangular parallelepiped shape, a protective member 2 that protects the analyzer main body 1, a restricting unit 3 that restricts vertical movement of a fixing member F, such as a belt, and a handle 4 that is attached to the side of the analyzer main body 1 and is gripped by an operator. Each part will be described below. Note that the roughly rectangular parallelepiped shape referred to here includes shapes similar to a rectangular parallelepiped, such as a shape with missing corners or a shape with chamfered corners, and shapes in which the surfaces that make up a rectangular parallelepiped are slightly uneven.

[0036] The analyzer body 1 analyzes sample gas sampled by a sampling unit (not shown). The analyzer body 1 has an analyzer (not shown) that analyzes the sample gas and a side panel that forms the side of the analyzer body 1.

[0037] The analyzer may 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 velocity of the sample gas. If the analyzer measures the concentration of the sample gas, the analyzer may be based on infrared absorption spectroscopy, such as non-dispersive infrared absorption (NDIR) or Fourier transform infrared spectroscopy (FTIR), hydrogen salt ionization detection, and / or other methods. If the analyzer analyzes the number of particles, the analyzer may be a condensation particle counter (CPC).

[0038] The side panel may be configured to be detachable from the analyzer main body 1. In this embodiment, the side of the analyzer main body 1 includes the front, rear, right side, and left side, assuming that the side on which piping such as hoses or connecting pipes, or connection terminals P electrically connected to each device, is attached is defined as the front of the analyzer main body 1. The connection terminals P include, for example, a sample gas introduction terminal for introducing sample gas into the analyzer main body 1, a power supply terminal to which power wiring from a power supply device (not shown) is connected, an information device terminal such as a LAN port for exchanging information and data with each device, and / or an adjustment gas introduction terminal to which calibration gas and / or purge gas is introduced.

[0039] The protective member 2 has a generally flat plate shape extending in the vertical direction and protects a corner 11 formed in the vertical direction by the side surfaces of adjacent analyzer body 1. In this embodiment, corner 11 refers to a portion formed between two adjacent side surfaces of analyzer body 1. More specifically, corner 11 refers to a portion cut out in the vertical direction from a top edge formed by connecting two adjacent side surfaces of the front, rear, right side, or left side of analyzer body 1. If the top edge is not cut out in the vertical direction, corner 11 may be the top edge itself.

[0040] The protective members 2 are provided independently at two or more corners 11. In this embodiment, as shown in Fig. 1, the protective members 2 are provided independently at all four corners 11. In this embodiment, the four protective members 2 have the same shape, but they may have different shapes.

[0041] 2 and 3, protective member 2 is provided at a distance from corner 11 so as to cover corner 11 in each side view forming corner 11, i.e., in a front view, a back view, and a side view. Specifically, protective member 2 is provided at a distance from corner 11 so as to cover corner 11 when viewed from a region formed by virtually extending each side surface forming corner 11 toward protective member 2.

[0042] Here, the protective member 2 is provided away from the corner 11 so as to cover the tip 11a of the corner 11 in a front view and a side view. Here, the tip 11a of the corner 11 refers to the surface or side on the tip side of the corner 11. More specifically, as shown in FIG. 4 , the tip 11a of the corner 11 is the surface or side that protrudes toward the outside of the analyzer body 1 and is located closest to the protective member 2.

[0043] In this embodiment, the protective member 2 has an opposing surface 2a that faces the tip portion 11a. As shown in Fig. 4, the length of the opposing surface 2a of the protective member 2 in the short side direction is longer than the width of the tip portion 11a.

[0044] The protective member 2 is provided on the analyzer 100 by being connected to mounting portions that are attached to the upper and / or lower surfaces of the analyzer 100. Specifically, as shown in Figures 2 and 3, the protective member 2 is connected to an upper mounting member S1 attached to the upper surface of the analyzer main body 1 and a lower mounting member S2 attached to the lower surface of the analyzer main body 1, and is thereby provided away from the corners 11. Note that in this embodiment, the protective member 2 is configured to be detachable from the upper mounting member S1 and the lower mounting member S2 and are separate members, but the protective member 2, the upper mounting member S1, and the lower mounting member S2 may also be the same member that is integrally formed.

[0045] As shown in FIGS. 1 and 5 , the protective member 2 has a through-hole 2b formed between the corner 11 and the protective member 2 for passing a fixing member F that fixes the analyzer main body 1 at a predetermined location. FIG. 5 is a partially enlarged cross-sectional view of the protective member 2 taken along the vertical direction through the center of the width direction, showing the portion through which the fixing member F passes. In this embodiment, the through-hole 2b is a space formed between the tip 11a and the opposing surface 2a of the protective member 2 by positioning the protective member 2 away from the corner 11. The distance between the corner 11 and the protective member 2 may be at least 30 mm or less. The distance between the corner 11 and the protective member 2 is preferably 0.1 mm or more and 20 mm or less. This allows the fixing member F, such as a belt, to pass through and prevents an operator's fingers from getting caught between the corner 11 and the protective member 2.

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

[0047] The restricting portion 3 has a columnar shape extending in the vertical direction and is provided between the corner portion 11 and the protective member 2. Specifically, as shown in FIGS. 5 and 6 , the upper surface and the lower surface of the restricting portion 3 are provided so that the distance between the upper surface of the restricting portion 3 and the upper end of the protective member 2 and the distance between the lower surface of the restricting portion 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 shown in FIGS. 5 and 6 , the upper surface or the lower surface of the restricting portion 3 functions as the restricting portion 3, restricting the vertical movement of the fixing member F. Note that in this embodiment, the restricting portion 3 is a separate member from the protective member 2, but the protective member 2 and the restricting portion 3 may be the same member formed integrally.

[0048] 4 and 5, the distance between the restricting portion 3 and the corner 11 is smaller than the distance between the protective member 2 and the corner 11. Specifically, as shown in FIGS. 4 and 5, the distance between the tip 11a and the opposing surface 3a of the restricting portion 3 that faces the corner 11 is smaller than the distance between the opposing surface 2a and the tip 11a of the protective member 2. With this configuration, the restricting portion 3 also functions as a finger pinch prevention portion that prevents an operator's fingers from getting pinched when the operator grasps the protective member 2 and the restricting portion 3.

[0049] Furthermore, as shown in Fig. 4, in a cross section perpendicular to the up-down direction, the restricting portion 3 has a shape that gradually narrows from the protective member 2 toward the corner 11. Specifically, as shown in Fig. 4, in a cross section perpendicular to the up-down direction, the protective member 2 has a rectangular shape, and the restricting portion 3 has a trapezoidal shape. Hereinafter, of a pair of parallel sides of the trapezoidal restricting portion 3, the side closer to the corner 11 will be referred to as the upper base, the side away from the corner 11 will be referred to as the lower base, and the other sides of the trapezoidal restricting portion 3 will be referred to as the leg sides.

[0050] As shown in FIG. 4, in a cross-sectional view perpendicular to the vertical direction, the upper and lower bases are parallel to the tip 11a of the corner 11, and the length of the upper base may be shorter than the length of the lower base. In addition, in a cross-sectional view perpendicular to the vertical direction, the angle formed between the surface constituting the leg and the side surface of the analyzer body 1 is preferably 90 degrees or less, and in this embodiment, the angle formed between the leg and the side surface of the analyzer body 1 may be 90 degrees. The length of the lower base may be the same as or different from the length of the protective member 2 in the width direction. Preferably, the length of the lower base is equal to or shorter than the length of the protective member 2 in the width direction.

[0051] The handle 4 is generally flat and is attached to the side panel of the analyzer body 1. As shown in Figures 2 and 3, the handle 4 is attached to the lower end of the side panel of the analyzer body 1 so as to be perpendicular to the longitudinal direction of the protective member 2. This allows an operator to attach or detach the side panel by holding the handle 4. Alternatively, a portion of the handle 4 may be attached away from the side panel, so that an operator can move the analyzer body 1 by holding the handle 4.

[0052] 4 and 7, both longitudinal ends of the handle portion 4 may be bent along the corners 11, and the outer peripheral surfaces of both longitudinal ends of the handle portion 4 are located on the same plane as the outer peripheral surface of the protective member 2. In this embodiment, the handle portions 4 are attached to all four side panels of the analyzer body 1. However, they need only be attached to at least two opposing side panels of the analyzer body 1; they do not have to be attached to all four side panels of the analyzer body 1. Here, when the handle portions 4 are attached to all four side panels, a heavy analyzer body 1 can be carried by multiple workers. On the other hand, in the case of a light-weight analyzer body 1, the handle portions 4 may be attached to two side panels.

[0053] <Effects of this embodiment> According to the analyzer 100 of this embodiment, the protective member 2 covers the corners 11 when viewed from each side that forms the corners 11, and this prevents the analyzer main body 1 from directly bumping into the surroundings when an operator moves the analyzer 100. As a result, the analyzer main body 1 and the devices housed in the analyzer main body 1 can be prevented from being damaged. In addition, a through portion 2b for passing the fixing member F is formed between the corner portion 11 and the protective member 2, so that the analysis device 100 can be fixed in a predetermined location by passing the fixing member F through the through portion 2b.

[0054] Furthermore, since the protective members 2 are provided independently at two or more corners 11, if a protective member 2 is damaged, it is only necessary to replace the damaged protective member 2, and there is no need to replace the other protective members 2, compared to when the protective members 2 protecting the respective corners 11 are formed integrally. In particular, in this embodiment, the protective members 2 are provided independently at all four corners 11, so that all four corners 11 can be protected, and it is also easier to replace the protective members 2 compared to when the protective members 2 that protect each corner 11 are formed as a single unit.

[0055] Furthermore, since two or more through-holes 2b are formed along the vertical direction, if the fixing member F is, for example, a belt, the worker can appropriately change the through-hole 2b through which the belt passes depending on the length of the belt.

[0056] In addition, the analysis device 100 further includes a regulating section 3 that regulates the vertical movement of the fixing member F, thereby preventing the fixing member F from falling downward, and enabling the fixing member F to fix the analysis device 100 even more stably.

[0057] Furthermore, since the distance between the restricting portion 3 and the corner portion 11 is smaller than the distance between the protective member 2 and the corner portion 11, it is possible to prevent the worker's fingers from getting caught at the location where the restricting portion 3 is provided.

[0058] Furthermore, when viewed in a cross section perpendicular to the vertical direction, the restricting portion 3 has a shape that gradually narrows from the protective member 2 toward the corner 11, making it easy for an operator to hook his / her fingers on the restricting portion 3 from the outside, and preventing the operator's fingers from getting pinched when hooking them on the restricting portion 3. Furthermore, in cross-sectional view, the restricting portion 3 has a shape that gradually narrows from the protective member 2 toward the corner 11, so that the restricting portion 3 cannot be seen from the outside, thereby improving the aesthetics and design of the analytical device 100.

[0059] In addition, the analysis device 100 is further provided with a handle portion 4 that is attached to a side panel that forms the side of the analysis device main body 1 and is gripped by an operator. Therefore, when it is necessary to remove the side panel, for example, to clean the inside of the analysis device 100, the side panel can be easily attached and detached by holding the handle portion 4.

[0060] <Other embodiments> The present invention is not limited to the above-described embodiment.

[0061] In the above embodiment, the protective member 2 has a generally flat plate shape, but the shape of the protective member 2 is not limited to this. The protective member 2 may have any shape as long as it covers the tip end 11a of the corner 11 when viewed from each side surface forming the corner 11, and may have other shapes such as a cylindrical shape or a hexagonal prism shape.

[0062] In the above embodiment, the protective members 2 are provided at all four corners 11, but it is sufficient that the protective members 2 are provided at at least two corners 11. Also, in the above embodiment, the protective members 2 are provided independently of each other, but the protective members 2 may be integrally formed to protect the respective corners 11.

[0063] In the above embodiment, two through-holes 2b are formed along the vertical direction, but this is not limited to this. One through-hole 2b may be formed, or three or more through-holes 2b may be formed.

[0064] In the above embodiment, the protective member 2 forms a through portion 2b between itself and the corner portion 11, but the protective member 2 may 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 was 0.1 mm or more and 20 mm or less, but as long as a fixing member F such as a belt can be passed through and an operator's fingers can be prevented from getting caught 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 numerical range.

[0066] In the above embodiment, the restricting portion 3 has a trapezoidal shape in a cross section perpendicular to the up-down direction, but it may have any shape that gradually narrows from the protective member 2 toward the corner 11. For example, the shape of the restricting portion 3 may be semicircular or other shapes in a cross section perpendicular to the up-down direction.

[0067] In the above-described embodiment, the upper mounting member S1 and / or the lower mounting member S2 may further include a positioning portion for positioning the other analytical device when the other analytical device is placed on the upper or lower surface of the analytical device main body 1. Specific examples of the positioning portion include an uneven shape formed on the surface of the upper mounting member S1 and / or the lower mounting member S2, and / or a hole for inserting a positioning pin into the upper mounting member S1 and / or the lower mounting member S2. This allows the other analytical device to be positioned by the positioning portion when placed on the upper or lower surface of the analytical device main body 1, thereby preventing the other analytical device from moving on the upper or lower surface of the analytical device main body 1. Note that all of the upper mounting members S1 and / or the lower mounting members S2 may include the positioning portion, or only some of the upper mounting members S1 and / or the lower mounting members S2 may include the positioning portion.

[0068] In the above embodiment, the analyzer 100 is configured to include the restricting portion 3 and the handle portion 4, but the analyzer 100 does not have to include the restricting portion 3 and the handle portion 4. Even in this case, it is possible to prevent the analyzer 100 from colliding with the surroundings and being damaged when the analyzer 100 is moved.

[0069] As another embodiment of the above-described embodiment, an analysis system 200 that analyzes exhaust gas from a specimen V may include the analysis device 100. Specifically, as shown in FIG. 8, the analysis system 200 may include a sampling unit 5 that samples exhaust gas from the specimen V, and an information processing device 6 that receives the analysis results analyzed by the analysis device 100 and processes the analysis results. Note that while FIG. 8 shows a case where the specimen V is a vehicle, the specimen V is not limited to a vehicle.

[0070] Here, the sampling unit 5 may include a tailpipe attachment 51 connected to the tailpipe of the vehicle, a flow meter 52 that measures the flow rate of exhaust gas, and an exhaust gas introduction pipe 53 that introduces exhaust gas from the tailpipe into the analysis device 100. The flow meter 52 measures the total amount of exhaust gas emitted from the test specimen V. The flow meter 52 may be, for example, a Pitot tube flow meter. The exhaust gas introduction pipe 53 introduces a portion of the exhaust gas emitted from the test specimen V into the analysis device 100. The information processing device 6 can calculate the mass and / or volume of a predetermined component contained in the exhaust gas based on the exhaust gas concentration measured by the analysis device 100 and the exhaust gas flow rate of the flow meter 52.

[0071] In FIG. 8, the analysis device 100 is placed on a mounting member B provided separately from the specimen V, and is fixed to the mounting member B via a fixing member F. Here, the mounting member B may be, for example, a rack and / or a shelf. The fixing member F is passed through the through-hole 2b of the analysis device 100 and attached to the support of the mounting member B, thereby fixing the analysis device 100 to the mounting member B. Note that, although the information processing device 6 is also placed on the mounting member B in FIG. 8, the information processing device 6 does not have to be placed on the mounting member B.

[0072] Furthermore, the analysis device 100 may further include a specimen testing device 7 for testing the specimen V. The specimen testing device 7 in Fig. 8 is a so-called chassis dynamometer that includes rollers 71 on which the specimen V is placed and a control device 72 that controls the rollers, but is not limited to this. The specimen testing device 7 may also be other specimen testing devices, such as an engine dynamometer or a drivetrain dynamometer.

[0073] Furthermore, as shown in FIG. 9 , in the analysis system 200, the analysis device 100 may analyze exhaust gas sampled by the sampling unit 5 while mounted on a test specimen V. In this case, a fixing member F is passed through the through-hole 2b and attached to the test specimen V, thereby fixing the analysis device main body 1 to a predetermined location M inside the test specimen V.
