Full-automatic chromaticity observation system

Abstract

The invention discloses a full-automatic chromaticity observation system, which is characterized by comprising a sample preprocessing module, a sample collection module, a character description system, a dilution module, a cleaning module, a color discrimination module and a data processing module, after the sample preprocessing module completes preprocessing, the sample is collected by the sample collection module and enters the character description system, the character description system outputs color, depth, transparency and pH value information to the data processing module, and a sample enters the sample temporary storage device after being processed by the character description system; after being diluted for multiple times by the dilution module and judged by the color judgment module, the data is output to the data processing module; according to the full-automatic chromaticity observation system, automatic solving measures are introduced, observation results can be objectively measured, the quantification degree is improved, and measurement errors caused by environmental factors are reduced.

Description

technical field [0001] The invention relates to the field of chemical experiments, in particular to an automatic chromaticity observation system. Background technique [0002] The prior art requires the experimenter to first pour the sample into a 250-milliliter graduated cylinder, let it stand for 15 minutes, and then take the supernatant for measurement. The first step is to carry out primary dilution, take 10 ml of the sample into a 100 ml colorimetric tube or volumetric flask, dilute it to the 100 ml mark with pure water, mix well, and pour the diluted sample and water into a 50 ml container respectively. Plug the colorimetric tube to the 50ml mark, place it vertically on a white surface, observe the liquid column vertically downward, and compare the color of the sample and water. If there is still color, continue to take 10 ml of the diluted sample, dilute it 10 times, and so on, until it is indistinguishable from water. The second step is natural dilution. Take the ...

Problems solved by technology

Each process needs to be manually operated, which is highly subjective, and the repeated operation process is time-consuming, resulting in waste of resources

This technology has high requirements on the experimental environment, a large number of repeated operations, and lack of automatic solutions. The experimental process requires visual colorimetry, which has a certain degree of subjectivity. There are differences in the measurement results among personnel. Objectively, the difference in the environment will also affect the detection. As a result, it is not conducive to quantitative evaluation
