Description

Technical Field

[0001] This invention relates to the field of infrared spectroscopy analysis technology, specifically to an infrared spectroscopy analysis device. Background Technology

[0002] Germanium tetrachloride is an important inorganic compound used to manufacture high-purity germanium single crystals, which are key materials for semiconductor devices. It is also used for vapor phase epitaxial deposition of germanium thin films to manufacture high-efficiency solar cells and optoelectronic devices.

[0003] Germanium tetrachloride needs to be placed in a sample cell for infrared spectroscopy detection. The sample cell consists of a quartz columnar cell and a germanium lens. An inlet pipe and an outlet pipe are connected to the quartz cell. The inlet and outlet pipes are sealed with simple, removable caps. The germanium lens is fixed with a steel ring and epoxy resin casting.

[0004] Since the height of the detection light source inside the infrared spectrometer cannot be changed, it is difficult to ensure that the germanium lens of each sample cell can correspond to the detection light source when different types of sample cells are placed inside the infrared spectrometer for detection, making it inconvenient to detect samples in different types of sample cells. Utility Model Content

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0007] This utility model provides an infrared spectroscopy analysis device, comprising:

[0008] An infrared analyzer includes a housing and a light source.

The support plate is connected to the adjusting component, and the clamping component is installed on the support plate. The clamping component can fix the sample cell. When the detection support is in the detection cavity, the adjusting component can drive the support plate to rise and fall to adjust the alignment of the sample cell with the light transmission hole.

[0012] In some embodiments, the base plate has multiple through holes.

[0013] In some embodiments, the clamping member includes two pressure plates and a bidirectional lead screw. Both pressure plates are slidably connected to the support plate, and the bidirectional lead screw is rotatably mounted on the support plate. The two threaded portions of the bidirectional lead screw are respectively threadedly rotatably connected to the two pressure plates, and an adjustable clamping space is formed between the two pressure plates.

[0019] Compared with the prior art, the infrared spectroscopy analysis device provided by this utility model has a detection cavity and a light-transmitting hole in the housing. The light-transmitting hole is connected to the detection cavity, and the light source is located inside the housing and corresponds to the light-transmitting hole. The detection bracket can move in and out of the detection cavity. The support plate is connected to the adjustment component, and the clamping component is installed on the support plate. In use, the detection bracket is first moved out of the detection cavity. After the clamping component fixes the sample cell, the detection bracket is moved into the detection cavity.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] To address the technical problem in existing technologies where the lens at the end of the sample cell aligns with the detection light source due to differences in sample cell models, this invention provides an infrared spectroscopy analysis device that allows adjustment of the sample cell so that the lens at the end of the sample cell is aligned with the detection light source, ensuring that the infrared spectroscopy analysis device is applicable to different sample cell models.

[0026] Please see Figures 1-4 , Figures 1-4 An infrared spectroscopy analysis device according to one embodiment of the present invention includes an infrared analyzer 1 and a detection support 2. The infrared analyzer 1 includes a housing 11 and a light source 12. The housing 11 has a detection cavity 11a and a light-transmitting hole 11b. The light-transmitting hole 11b is connected to the detection cavity 11a. The light source 12 is disposed inside the housing 11 and corresponds to the light-transmitting hole 11b. The detection support 2 can enter and exit the detection cavity 11a. It includes an adjusting member 21, a support plate 22, and a clamping member 23. The support plate 22 is connected to the adjusting member 21. The clamping member 23 is installed on the support plate 22 and can fix the sample cell. When the detection support 2 is in the detection cavity 11a, the adjusting member 21 can drive the support plate 22 to rise and fall to adjust the alignment of the sample cell with the light-transmitting hole 11b.

[0027] In actual use, the detection bracket 2 is first moved out of the detection cavity 11a, and the sample cell is fixed by the clamping member 23. Then the detection bracket 2 is moved into the detection cavity 11a, and the adjusting member 21 adjusts the height of the support plate 22 so that the lens at the end of the sample cell corresponds to the light transmission hole 11b.

[0028] The sample cell is a sample cell for infrared detection of germanium tetrachloride and silicon tetrachloride disclosed in the existing patent application document CN103900960A, and the sample contained in the sample cell is germanium tetrachloride.

[0029] It should be noted that the adjusting component 21 is not limited to a specific structure, as long as it can adjust the installation height of the sample cell, no other limitations are made here.

[0030] In one embodiment, the adjusting member 21 includes a seat 211 and a threaded screw 212, the threaded screw 212 being rotatably mounted on the seat 211, and the support plate 22 being slidably connected to the seat 211 and threadedly rotatably connected to the threaded screw 212.

[0031] It is understandable that by manually rotating the threaded screw 212, the testing personnel can drive the support plate 22 to rise or fall, thereby adjusting the height of the sample pool on the support plate 22.

[0032] In one embodiment, the seat 211 is generally L-shaped, and the seat 211 includes a base plate 2111 and a vertical plate 2112. The vertical plate 2112 is fixedly connected to the base plate 2111, the threaded screw 212 is rotatably mounted on the vertical plate 2112, and the support plate 22 is slidably connected to the vertical plate 2112.

[0033] It should be noted that when the detection bracket 2 is placed in the detection cavity 11a, the base plate 2111 is in contact with the inner bottom wall of the detection cavity 11a, and the vertical plate 2112 is in contact with one inner side wall of the detection cavity 11a. In addition, the base plate 2111 is provided with multiple through holes, and the vertical plate 2112 can also be provided with multiple through holes. By providing multiple through holes, the mass of the base 211 can be reduced.

[0034] It should be noted that the clamping member 23 is not limited to a specific structure, as long as it can clamp the sample cell, no other limitations are made here.

[0035] In one embodiment, the clamping member 23 includes two pressure plates 231 and a bidirectional lead screw 232. Both pressure plates 231 are slidably connected to the support plate 22. The bidirectional lead screw 232 is rotatably mounted on the support plate 22, and the two threaded portions of the bidirectional lead screw 232 are respectively threadedly rotatably connected to the two pressure plates 231. An adjustable clamping space is formed between the two pressure plates 231.

[0036] Understandably, by rotating the bidirectional lead screw 232, the testing personnel can drive the two pressure plates 231 to move closer or further apart, thereby fixing the sample cell between the two pressure plates 231.

[0037] Based on the above scheme, a gasket is provided on the side of the two pressure plates 231 that are close to each other. The gasket is an elastic rubber gasket, so that the sample cell is fixed between the two pressure plates 231 without shaking.

[0038] Based on the above scheme, in order to facilitate the pretreatment of samples before detection, a gas delivery mechanism 3 is specifically included. The gas delivery mechanism 3 is connected to the detection chamber 11a, and the gas delivery mechanism can deliver nitrogen gas into the detection chamber 11a.

[0039] It is understandable that after aligning the lens at the end of the sample cell with the light-transmitting hole 11b, nitrogen gas is continuously delivered to the detection chamber 11a through the gas delivery mechanism 3 to purge the detection chamber 11a.

[0040] The gas delivery mechanism 3 includes a hydrogen storage tank and a gas delivery pipe. The hydrogen storage tank stores nitrogen gas. A control valve is installed at the outlet of the hydrogen storage tank, and one end of the gas delivery pipe is connected to the control valve. After the control valve is opened, the nitrogen gas can be delivered to the detection chamber 11a through the gas delivery pipe.

[0041] In one embodiment, the housing 11 is further provided with a gas guiding cavity, and the gas guiding cavity is connected to the detection cavity 11a via a plurality of the gas vents 11c. The gas guiding cavity is connected to the gas delivery mechanism 3. It should be noted that by delivering nitrogen gas to the detection cavity 11a through the gas vents 11c, the nitrogen gas can be evenly dispersed throughout the entire detection cavity 11a.

[0042] Based on the above scheme, the infrared analyzer 1 also includes a cover plate 13, which is hinged to the housing 11. The cover plate 13 is used to open and close the opening of the detection chamber 11a. At least one elastic band 131 is provided on one side of the cover plate 13, which can fix the desiccant pack to the cover plate 13.

[0043] It is understandable that when the infrared analyzer 1 is not in use, the opening of the detection chamber 11a can be opened and closed through the cover plate 13. At this time, the desiccant pack is located at the opening of the detection chamber 11a. The desiccant can keep the inside of the detection chamber 11a dry and reduce the influence of external factors on sample detection.

[0044] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
