Microcoulometric sulfur chlorine analyzer

Microcoulometric sulfur chlorine analyzerOverview:

The KVD-600 microcoulometric titrator is a new generation instrument developed based on the KVD-200 microcoulometric titrator, which adopts the principle of dynamic microcoulometric titration. The sample to be tested undergoes oxidation-reduction reaction through combustion in the cracking tube, and is carried into the titration cell by the carrier gas to convert into titratable ions, which react with the electrically generated I3- or Ag+. By measuring the amount of I3- or Ag+consumed during the electrolytic titration process, the total sulfur or total chlorine content of the sample can be obtained according to Faraday's law.

Scope of application: Used for the analysis of total sulfur or total chlorine content in samples in the production, scientific research, and monitoring fields of petroleum, petrochemicals, pharmaceuticals, health, environmental protection, coal, geology, metallurgy, commercial inspection, quality inspection, and schools.
