Abstract

The invention provides a reaction device for photometric colorimetric method detection and a detection method. The reaction device comprises a reaction main body unit, a detection unit, a liquid inletunit and a stirring unit. The detection unit comprises a light source emitting part and a light source signal collecting part; two opposite openings are formed in the side wall of the bottom of a reaction cup base; and the light source emitting part and the light source signal collecting part are embedded into the two openings respectively. A light source emitted by the light source emitting partirradiates a solution in the reaction cup to send a light intensity signal to the light source signal collecting part. According to the invention, the end point, namely a chemical variable point, oftitration analysis is accurately judged through a photometric colorimetric method, so that the concentration of liquid medicine is accurately and automatically analyzed.

Description

technical field [0001] The invention belongs to reaction equipment for reagent concentration detection, in particular to a reaction device and a detection method for photometric colorimetry detection. Background technique [0002] With the increasing standard requirements of industrialization, the accuracy requirements of solution concentration detection are becoming more and more stringent. The traditional detection method records data after adding the reaction reagent. The detection accuracy of this method is not high, and the structure of the reaction device is complicated. The assembly is troublesome, the detection accuracy of photometric colorimetry is not high, and there is also the problem of cross-contamination between reagents. The patent number CN201920567541.0 submitted by the applicant earlier is called an automatic online detection device. The reaction device in the automatic online detection device is based on the color of the substance to be tested or the colo...
