Abstract

The invention belongs to a chemical ingredient detecting device in the technical field of chemical detection. The chemical ingredient detecting device is composed of an inner core 1, a jacket 2 and ahandle 3. Two ends of the jacket 2 are open and sleeve the lower part of the inner core 1. The upper end of the inner core 1 is connected to the handle 3. The upper part of the inner core 1 is provided with an end point area 6. Detection areas 4 are arranged below the end point area 6. An isolation area 5 is disposed between the detection areas 4 and the end point area 6. An isolation area 5 is disposed between the detection areas 4. The end point area 6 contains a substance that can be discolored or developed in water or solvent. The detection area 4 contains a specific reagent or a color developing agent. The isolation areas 5 are blank zones. The chemical ingredient detecting device solves the problem that the existing chemical component detecting device has complicated operation and asmall application range, or utilizes expensive instruments, and detects a single component. The chemical ingredient detecting device has the advantages of simple structure, low cost, simple method, easy operation and no professional training, fast and in-situ detection and wide application range.

Description

Technical field [0001] The invention belongs to the technical field of chemical detection, and in particular relates to a chemical component detection device. Background technique [0002] Chemical composition detection methods can be divided into two categories: chemical analysis and instrumental analysis. Chemical analysis is a classical analysis method based on the chemical reaction of substances, mainly including gravimetric analysis, titration analysis and colorimetric analysis. The colorimetric analysis method is based on the color of the component to be tested in the sample itself or the colored substance generated by the component reacting with a specific reagent or chromogenic agent, and the qualitative and quantitative determination of the component to be tested is determined by comparing or measuring the color depth. Analytical method. Colorimetric analysis belongs to the category of spectroscopic analysis, which has the advantages of sensitivity, rapidity, accu...
