The arsenic content analyzer adopts the principle of microcoulometric titration. It extracts the organic arsenic compounds in the sample with acid, converts them into inorganic arsenic and reduces them to AsH3. It reacts with the titrant in the titration tank, measures the amount of electricity required to supplement the titrant, and calculates the arsenic content according to Faraday's law.

CAs-6000 Coal Arsenic Tester is a new product designed by our company according to the "GB/T 3058-2008 Determination of Arsenic in Coal". It uses a monochromatic cold light source, utilizes a microcomputer to automatically process data, and directly displays the arsenic ion concentration value of water samples; The arsenic content analyzer is applicable to the determination of arsenic content in various oil products such as lignite, bituminous coal, anthracite, gasoline, diesel, light and heavy naphtha, crude oil, residual oil, liquefied gas, propylene gas, and various catalysts. It is also applicable to the determination of arsenic content in various water, food, beverage, and other samples.
