[0002] Chemical analyzer is an important equipment used to analyze the composition or properties of substances in chemical experiments and industrial production. It has the characteristics of high precision, high efficiency, and high degree of automation. It can greatly save manpower and time costs and improve the accuracy and reliability of analysis results.

[0003] Online wet chemical analyzers have the advantages of high precision, real-time monitoring, and a high degree of automation. They can improve production efficiency, reduce failure rates, and save costs for enterprises. Wet chemistry usually refers to chemical reactions or treatment processes carried out in a liquid environment, such as wet etching, wet desulfurization, etc. Wet chemical analysis is based on the chemical reactions of substances. The components and their contents in the sample are directly determined by the reaction results. A separate booth is used to perform online testing on a single sample. When multiple samples are tested in sequence, multiple filling operations are performed, which can easily cause water pollution and affect the overall online detection effect.
