Product Overview:

The instrument applies the principle of microcoulometry titration and computer-controlled data acquisition and processing. The sample is injected into the lysis tube by an automatic sampler for reaction, and the tested element is converted into titratable ions, which are carried into the titration cell by a carrier gas for titration. The titrant in the electrolyte is consumed, and an equal amount of titrant is generated and consumed. The amount of electricity consumed during the electrolysis process is measured, and the content of the tested element in the sample is calculated according to Faraday's law. According to different configurations, the content of sulfur or chlorine in the sample can be measured separately.
