SDS720 Coulomb Sulfur Analyzer

Our SDS720 can be used to determine the total sulfur content in combustibles such as coal, coke, petroleum, and other solid biomass fuels in the field of power plants, coal mining, cement and steel companies, environmental industry.

A sample combusts and decomposes in air current with a catalyst, the sulfur in coal produces sulfide in the reaction, and among the products, the sulfur dioxide is absorbed by potassium iodide (KI) solution. Titrate the iodine produced by electrolyzing potassium iodide, and calculate the total sulfur content in coal according to the quantity of electricity consumed when electrolyzing.
