This microcoulometry comprehensive analyzer adopts dynamic microcoulometry principle, which adopts oxidation method to oxidize the sample to titratable ion through cracking furnace. It titrates in titrating cell and calculates out the sulfur or chlorine content in sample according to the consumed electricity quantity during titration process and the Faraday's law. It has stable and reliable performance, easy operation, high analysis accuracy and good repeatability. It is widely applied to petroleum, chemical industry, environmental protection, geology, metallurgy, scientific research, teaching etc. |
