JCBLC-2003A Microcomputer-Based Sulfur-Chlorine Analyzer
The instrument operates on the principle of dynamic microcoulometry. The sample to be analyzed is combusted in a pyrolysis tube, where redox reactions occur; the resulting products are carried by the carrier gas into the titration cell, where they are converted into titratable ions and react with electrogenerated I3⁻ or Ag⁻. By measuring the charge consumed during the electrolytic titration of I3⁻ or Ag⁻, and applying Faraday’s law, the total sulfur or total chlorine content of the sample can be determined.

Overview:
◆ The instrument operates on the principle of dynamic microcoulometry. The sample to be analyzed is combusted in a pyrolysis tube, where redox reactions occur; the resulting products are carried by the carrier gas into the titration cell, where they are converted into titratable ions and react with electrogenerated I3⁻ or Ag⁻. By measuring the electric charge consumed during the electrolytic titration of I3⁻ or Ag⁻, and applying Faraday’s law, the total sulfur or total chlorine content of the sample can be determined.
◆ Scope of application: Used for the determination of total sulfur or total chlorine content in samples across various sectors, including petroleum, petrochemicals, pharmaceuticals, healthcare, environmental protection, coal, geology, metallurgy, commodity inspection, quality inspection, and education.
