Microcoulometric sulfur and chlorine analyzer PKL-2000GY Type
- Overview:
PKL-2000GY Microcoulomb sulfur-chloride analyzer (PKL-2000 microcoulomb titrator) is a new generation of sulfur-chloride analysis instrument developed on the basis of PKL-200 microcoulomb titrator, which adopts the principle of dynamic microcoulomb. The sample to be tested is burned in the pyrolysis tube to undergo redox reaction, which is converted into titratable ions by the carrier gas into the titration cell, and reacts with the electrogenerated I3- or Ag+, and the total sulfur or total chlorine content of the sample can be obtained according to Faraday’s law by measuring the amount of I3- or Ag+ consumed during the electrolytic titration process.
Scope of application: used for the analysis of total sulfur or total chlorine content of samples in production, scientific research and monitoring fields such as petroleum, petrochemical, medicine, health, environmental protection, coal, geology, metallurgy, commodity inspection, quality inspection, and schools.
