3 Method summary

Sample in a high frequency induction furnace combustion heating large stream of oxygen, carbon conversion to carbon dioxide (or carbon monoxide), transformed into sulfur dioxide Oxygen introduced by the infrared detector measures the room, the detection of carbon dioxide (or carbon monoxide) and sulfur dioxide absorption of specific wavelengths of infrared energy, Concentration can be absorbed carbon and sulfur and is proportional to the measured total carbon and sulfur content.
