Principle of Oxygen and Nitrogen Analyzer
The oxygen and nitrogen analyzer can decompose samples by pulse heating under an inert atmosphere, and determine the content of oxygen and nitrogen in various steels, non-ferrous metals, and new materials using a non-dispersive infrared detector and a thermal conductivity detector respectively.
