3 Principle

The sample is heated and burned in the oxygen flow of the high-frequency induction furnace, and the sulfur-generated sulfur dioxide is carried by the oxygen to the measuring chamber of the infrared analyzer. Sulfur oxide absorbs infrared energy of a specific wavelength, and its absorption energy is proportional to its concentration, and the sulfur content can be determined according to changes in the energy received by the detector.
