In order to better utilize the water and prevent the water from being contaminated, it is necessary to fully grasp the water quality status! Perform the correct water quality analysis. With the advancement of science and technology, various modern means have been applied in water quality monitoring and analysis. The electrochemical analysis method is an analytical method for determining the content of a substance component based on electrical and electrochemical properties of a substance in a solution, such as electrical signals such as potential, charge, current, resistance, and the like; and a conductivity meter for measuring the conductance of water. rate. The pH meter or ion meter measures the hydrogen ion or other ion concentration of the water sample, and the potentiometric titration of the end point of the titration is indicated by the potential jump of the solution at the end of the titration. The separation method uses instruments (such as chromatography #electrophoresis) to separate and analyze compounds that are structurally and qualitatively similar, mainly based on chromatography and electrophoresis techniques. Classical wet chemical analysis can only measure parameters individually using different methods, and has low sensitivity, high interference, and lengthy steps. Using the TitIC method, multiple indicators can be measured simultaneously, with accurate results and high reproducibility, which greatly saves manpower and time.
