Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of absorbance detection, in particular to a special photometric tooling for an ultraviolet spectrophotometer. Background Art
[0002] An ultraviolet spectrophotometer is an instrument used to measure the absorbance of a substance to be measured to visible light and perform quantitative analysis. The existing ultraviolet spectrophotometer uses a transparent container to hold the irradiated color-changing liquid to be measured, and automatically detects the absorbance of the liquid before and after irradiation according to the principle of spectrophotometry, and then calculates the absorbance dose of the liquid; however, for an irradiated color-changing film with an organic material as the base material and a dye coated on the surface, the ultraviolet spectrophotometer cannot be used to automatically detect its absorbance dose, resulting in great limitations in the use of the ultraviolet spectrophotometer and limited popularization and application. Summary of the Invention
[0003] The purpose of the utility model is to provide a special photometric tooling for an ultraviolet spectrophotometer aiming at the defects of the prior art.
[0004] To achieve the above purpose, the utility model can adopt the following technical solutions:
[0005] The special photometric tooling for an ultraviolet spectrophotometer of the utility model includes a support plate, on which a pair of loading seats are arranged at intervals. The loading seats are provided with rectangular loading cavities with upper openings, and strip-shaped through holes communicating with the rectangular loading cavities are symmetrically arranged on the front and rear side walls of the loading seats; a transparent loading box for holding the irradiated color-changing liquid is adaptively inserted into one of the rectangular loading cavities. The transparent loading box is a quartz cuvette or a glass cuvette with a rectangular cross-section. An opaque loading column is adaptively inserted into the other rectangular loading cavity. A thin film slot for inserting the irradiated color-changing film is vertically opened downward on the top surface of the opaque loading column. Through holes corresponding to the strip-shaped through holes are coaxially arranged on the opaque loading columns on both sides of the front and rear of the thin film slot.
[0006] Further, a strip-shaped adjusting slot hole is opened on the loading seat. The length direction of the adjusting slot hole is consistent with the length direction of the support plate. A pressing bolt with the lower end screwed and fixed to the support plate is vertically inserted into the adjusting slot hole. The loading seat is fixed to the support plate through the pressing bolt passing through the adjusting slot hole, and the installation position of the loading seat on the support plate can be adjusted according to the use requirements.
[0007] The advantages of the utility model lie in its simple structure, convenient use and low manufacturing cost. Through a pair of loading seats arranged side by side on the support plate, and a transparent loading box and an opaque loading column adaptively inserted into the two loading seats, it is thus adapted to the ultraviolet spectrophotometer, easily completing the absorbance detection of the irradiation color-changing liquid and the irradiation color-changing film, ensuring the accuracy of the detection results, expanding the use limitations of the ultraviolet spectrophotometer, forming a detection tooling that is simultaneously adapted to the irradiation color-changing liquid and the irradiation color-changing film, and realizing the efficient and convenient tooling detection of the irradiation color-changing liquid and the irradiation color-changing film. Brief Description of the Drawings
[0008] Figure 1 is a schematic structural diagram of the utility model. Detailed Embodiment
[0009] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
[0010] It should be noted that all the directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.
[0011] As Figure 1 shown, the special photometric tooling for the ultraviolet spectrophotometer described in the present utility model includes a support plate 1 with a rectangular structure. Along the length direction of the support plate 1, a pair of loading seats 2 are arranged at intervals. The loading seat 2 is provided with a rectangular loading cavity 3 with an upper opening structure. Symmetrically arranged on the front and rear side walls of the loading seat 2 are strip-shaped through holes 4 communicating with the rectangular loading cavity 3. A transparent loading box 5 is adaptively inserted into one rectangular loading cavity 3, and an opaque loading column 6 is adaptively inserted into the other rectangular loading cavity 3. Specifically, the transparent loading box 5 is a quartz cuvette or a glass cuvette with a rectangular cross-section, and the opaque loading column 6 is an acrylic solid column with a rectangular cross-section. In addition, a thin film slot 7 is vertically opened downward on the top surface of the opaque loading column 6, and light-transmitting through holes 8 corresponding to the strip-shaped through holes 4 are coaxially opened on the opaque loading column 6 on the front and rear sides of the thin film slot 7.
[0012] During use, the irradiation discoloration liquid to be tested is contained in the transparent holding box 5, and the transparent holding box 5 is inserted onto one of the holding seats 2. The irradiation discoloration film coated with dye is inserted through the film slot 7 on the light-tight carrier column 6, and the light-tight carrier column 6 is inserted onto the other holding seat 2. Thus, the support plate 1 can be directly placed in the ultraviolet spectrophotometer, enabling the ultraviolet detection light of the ultraviolet spectrophotometer to pass through the strip-shaped perforations 4 and irradiate the irradiation discoloration liquid to be tested in the transparent holding box 5 and the irradiation discoloration film exposed in the light-transmitting through holes 8. Furthermore, the absorbance detection of the irradiation discoloration liquid and the irradiation discoloration film can be easily completed, ensuring the accuracy of the detection results, expanding the usage limitations of the ultraviolet spectrophotometer, forming a detection tooling that is simultaneously adapted to the irradiation discoloration liquid and the irradiation discoloration film, and realizing the efficient and convenient tooling detection of the irradiation discoloration liquid and the irradiation discoloration film.
[0013] In addition, to facilitate the adjustment of the distance between the two holding seats 2, connecting wing plates 9 should be extended and provided on the bottom of the outer wall of the holding seat 2 to the left and right sides, and adjustment slot holes 10 with a strip-shaped structure should be opened on the connecting wing plates 9. The length direction of the adjustment slot holes 10 should be consistent with the length direction of the support plate 1. A compression bolt 11 with its lower end screwed and fixed to the support plate 1 is vertically inserted through the adjustment slot holes 10. The holding seat 2 is fixed to the support plate 1 through the compression bolt 11 passing through the adjustment slot holes 10. Thus, the installation position of the holding seat 2 on the support plate 1 can be adjusted according to the usage requirements, realizing the fine adjustment of the distance between the two holding seats 2, and enabling the two holding seats 2 to more precisely match the ultraviolet spectrophotometer.
