4F - S Combustion Infrared detection
Accelerator material is added
to a
0.2 g sample. The inductive elements of the sample and accelerator couple with the high frequency field of the induction furnace. The pure oxygen environment and the heat generated by this coupling cause the sample to combust. During combustion, sulphur-bearing elements are reduced, releasing sulphur, which binds with oxygen to form SO2. Sulphur is measured as sulphur dioxide in the infrared cell. An Eltra CS-2000 or a Leco CNS 2000 is used for analysis.
