HIGHLIGHTS

Coulomb Sulfur Analyzer working principles:
A sample combusts and decomposes in air current with catalyst, the sulfur in coal produces sulfide in the reaction, and among the products, the sulfur dioxide absorbed by potassium iodide (KI) solution . Titrate the iodine produced by electrolyzing potassium iodide, and calculate the total sulfur content in coal according to quantity of electricity consumed when electrolyzing.
The total sulfur content, St, ad, of the sample, expressed as a percentage by mass, is given by the equation below:
St, ad=m1/m×100
Where
St, ad is total sulfur content in general analysis samples, expressed as a percentage by mass, %;
m1 is displayed in coulomb integrator, expressed in milligram, mg;
m2 is the mass of the sample, expressed in milligram, mg.

  • Horizontal furnace with a super wide uniform temperature zone(≥90mm) ensures complete combustion of coal samples.
  • Dilated and thickened electrolysis electrodes, with bigger interface, make the integration more accurate and complete.
  • With CAN bus, several calorimeters can be controlled by a single PC without mutual influence.
  • Balance could be connected and data could be transmitted by real-time network transmission.
