Сhromatographs are used to analyze the purity of gases (oxygen, hydrogen, krypton, argon, helium, xenon) in metallurgy. Substances can be used both in liquid and gaseous state. Chromatographic equipment also enables to analyze argon impurities or hydrocarbon impurities in oxygen. Metals Manufacturing use chromatographs to analyze blast furnace products, which include pig iron. Gas chromatographic methods make it possible to determine the component composition of phenol coal, pyridine coke chemical products, as well as coal oils. Chromatographic equipment manufactured by Meta-Chrome perfectly copes with these and many other analytical tasks.
