Embodiment Construction

[0019] Such as figure 1 with 2 , The embodiment of the photoelectric detection device proposed by the present invention mainly includes: a support 1 , a cuvette 2 , a light source 3 , a receiver 4 and a magnetic stirrer 7 .

[0020] Wherein, both the support 1 and the cuvette 2 adopt an integrated structure to enhance stability. The cuvette 2 is fixed in the middle of the support 1 by threaded connection, for example: the cuvette 2 is fixed on the support 1 by screws, and one or more installation holes can be pre-designed on the support 1 during specific implementation. Then, the cuvette 2 is fixed on the installation hole by screws, so that the cuvette 2 is fixed in the middle of the support 1 . The advantage of adopting the method of threaded connection is that when the fixing strength of the cuvette 2 is ensured, the cuvette 2 can be easily disassembled from the support 1, so as to facilitate the comparison cuvette 2 and cleaning and maintenance.

[0021] Wherein, the cu...

Abstract

The invention relates to a photoelectric detection device. The photoelectric detection device comprises a support, a cuvette, a light source and a receiver, wherein the cuvette is fixed to in the middle of the support in a manner of threaded connection; and the light source and the receiver are fixed on the support and are positioned on both sides of the cuvette. The invention also provides a hydrazine analyzer with the photoelectric detection device structure. The cuvette in the photoelectric detection device is fixed on the support in the manner of threaded connection, so that the photoelectric detection device is easy to disassemble in structure, and the cuvette is convenient to manually clean and maintain.

Description

technical field [0001] The invention relates to hydrazine analysis technology, in particular to a photoelectric detection device and a hydrazine analyzer used in hydrazine analysis. Background technique [0002] At present, the colorimetric method is mainly used as the main measurement method in the hydrazine analyzer. The measurement principle of the colorimetric method is: under acidic conditions, hydrazine reacts with p-dimethylbenzaldehyde to generate a yellow azo compound, and the depth of the yellow color within the measurement range is proportional to the content of hydrazine, which conforms to Lambert-Beer Law, and the maximum absorption wavelength of azo compounds is 454nm, so the content of hydrazine can be obtained by measuring the depth of yellow. At present, the device that realizes colorimetry is mainly a photoelectric detection device, which mainly includes: a cuvette, a monochromatic light source, and a receiver. During measurement, hydrazine and p-dimethylb...
