Sections
Test Method A
High-Temperature Combustion With In-
frared Absorption Detection Procedures

6. Summary of Test Method
6.1 The specimen is burned in a tube furnace at a minimum operating temperature of 1350°C in a stream of oxygen to oxidize
the sulfur. Moisture and particulates are removed from the gas by traps filled with anhydrous magnesium perchlorate. The gas
stream is passed through a cell in which sulfur dioxide is measured by an infrared (IR) absorption detector. Sulfur dioxide absorbs
IR energy at a precise wavelength within the IR spectrum. Energy is absorbed as the gas passes through the cell body in which
the IR energy is being transmitted. Thus, at the detector, less energy is received. All other IR energy is eliminated from reaching
the detector by a precise wavelength filter. Thus, the absorption of IR energy can be attributed only to sulfur
