Colorimeter for measuring concentration of monochromatic solution

Abstract

The invention provides a colorimeter for measuring the concentration of a monochromatic solution. The colorimeter comprises a sample bearing part, a light emitting assembly, an image acquisition assembly, a camera obscura, and a colorimetric module. The image acquisition assembly is used for acquiring a color image of the to-be-detected sample under the light irradiation of the light-emitting assembly, so that the colorimetric module can be used for colorimetrically determining the concentration. The color depth characterization value of the color image is extracted by collecting the color image of the to-be-detected sample, and the concentration of the to-be-detected sample is obtained according to the relational expression between the color depth characterization value and the solution concentration, so that the method is simple to operate, can be applied to measurement of concentrations of various different types of monochromatic solutions, and is wide in application range. A plurality of to-be-detected samples can be placed on the sample bearing part at the same time according to needs, after corresponding color images are collected at the same time, color depth characterization values of the corresponding images are extracted in sequence, corresponding concentration values are matched, high-flux quantitative analysis can be achieved, and the speed is high.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a colorimeter for measuring the concentration of a single-color solution. Background technique [0002] Colorimetric analysis is to use the color of the tested colored solution itself, or the color presented after adding reagents, to observe and compare the color depth of the colored solution with the eyes (or a visual colorimeter), or to measure with a photoelectric colorimeter to determine the color of the colored solution. The method of measuring the concentration of the substance in the test. At present, the commonly used method is generally to use the principle of spectrophotometer for colorimetric analysis. By setting up laser transmitters and receivers on both sides of the container holding the sample to be tested, by measuring the light absorption of the colored solution at a specific wavelength or within a certain wavelength range, To analyze the concentration of the ...

Problems solved by technology

This method can only be operated in a single order, and this structure can only be used for point measurement, not for space measurement. When the number of samples to be tested is large, it is necessary to increase the transmission structure to transport different samples to be tested to the detection position. Not suitable for flux detection
