Problems solved by technology

[0002] At present, on-site analyzers related to water quality, environment or food use one detection mode to analyze one or more parameters, which has low efficiency and high cost, and the optical path detection mode is relatively single, and colorimetry, fluorescence and scattering modes cannot be realized. The light source design of the traditional colorimetric measurement device is generally a single-side light source setting....

Embodiment Construction

[0013] A multi-parameter analysis colorimetric measurement device, comprising a colorimetric cell 1 and a light source 5, the colorimetric cell 1 is a solid cube, a groove for placing a cuvette 2 is left in the middle of the cuvette 1, and the outer walls of the cuvette 1 are Slots 4 are arranged on the upper adjacent two sides, and light sources 5 of four different wave bands are embedded side by side on the slots 4, and a photodetector 3 is respectively installed in the center of the other two adjacent sides, and the interior of the colorimetric cell 1 corresponds to Each light source 5 is provided with an optical channel 6, and the optical channel 6 converges at the groove and extends to the opposite photodetector 3.

[0014] Further, the light source 5 is a single-wavelength light-emitting diode and / or a dual-wavelength light-emitting diode.

[0015] Further, an optical filter is added in front of each light source in the optical channel 6 .

[0016] Further, there is a g...

Abstract

The invention relates to a multi-parameter analysis colorimetric measurement device which comprises a colorimetric pool and light sources. The colorimetric pool is a solid cube, a groove containing a colorimetric ware is reserved in the middle of the colorimetric pool, slots are formed in the two adjacent side faces of the outer wall of the periphery of the colorimetric pool, the light sources of four different wave bands are embedded into the slots side by side, photoelectric detectors are installed in the centers of the other two adjacent side faces respectively, an optical channel corresponding to each light source is formed in the colorimetric pool, and the optical channels are converged at the groove and extend to the photoelectric detectors at the opposite side. The device provides 16 groups of wave lengths, by starting the light sources on different side faces and the photoelectric detectors, colorimetric detection, fluorescent detection, scattering detection and the like can be achieved, and detection of more than 100 detection items can be met.

Description

technical field [0001] The invention relates to a colorimetric measuring device, in particular to a colorimetric measuring device capable of measuring multiple parameters. Background technique [0002] At present, on-site analyzers related to water quality, environment or food use one detection mode to analyze one or more parameters, which has low efficiency and high cost, and the optical path detection mode is relatively single, and colorimetry, fluorescence and scattering modes cannot be realized. The light source design of the traditional colorimetric measurement device is generally a single-side light source setting. Due to the single detection mode, even if multiple sets of single-side light source settings can complete the detection items, it is very limited, which seriously affects the application of the colorimetric measurement device. range, and the interference of the turbidity and chromaticity of the solution itself on the sample determination cannot be eliminated...
