CS-320 Polar adopts high-frequency furnace heating, infrared absorption detection systems. The samples are heated in oxygen condition, causing carbon and sulfur in the sample to react to CO2 and SO2. At the same time, trace CO is generated. The generated oxide is purified or catalyzed and passes into the infrared detection system. Using CO2 and SO2 at 4.26m and 7.4m, where there is a strong characteristic absorption band, the absorbed infrared light intensity is measured to calculate the percentage of carbon and sulfur elements in samples.
