Product Overview:

The TAS-2000 microcomputer arsenic analyzer is designed using the principle of microcoulometry titration. It extracts organic arsenic compounds from the sample with acid, converts them into inorganic arsenic, and reduces them to AsH3. It reacts with the titrant in the titration cell, measures the amount of electricity required to supplement the titrant, and calculates the arsenic content based on Faraday's law.

Suitable for the determination of arsenic content in various oil products such as gasoline, diesel, light and heavy naphtha, crude oil, residue oil, liquefied gas, propylene gas, and various catalysts. The instrument is also suitable for determining arsenic content in various water, food, beverage and other samples.
