The microcoulometric chlorine analyzer is based on the national standard GB/T18612-2011. According to the microcoulometric principle, all forms of chlorine in the sample are converted into HCl at high temperatures in nitrogen and oxygen, and enter the titration cell. In the cell, silver ions are produced through electrolysis and react with chloride ions. The microcomputer automatically calculates the total chlorine content in the sample based on the electricity consumed by the silver ions and Faraday's law. The entire analysis process is controlled by a computer, and the samples are loaded by an automatic sampler, with a high degree of instrument automation. It can be used for the analysis of trace chlorine in petrochemical products and is widely used in industries such as petroleum, chemical, scientific research, teaching, environmental protection, quality inspection, and commercial inspection.
