GC-9870 Zirconia Gas Chromatography (Food Grade Nitrogen)

Zirconia gas chromatograph is a chromatographic analysis instrument that uses zirconia solid electrolyte primary cells as detectors, specifically designed to analyze the content of trace amounts of hydrogen, oxygen, methane, and carbon monoxide in high-purity inert gases. It has the characteristics of high sensitivity, high selectivity, and simultaneous analysis of multiple components in one injection. It can be equipped with a hydrogen flame ionization detector according to user needs, and can also detect carbon dioxide and total hydrocarbons. It is a very practical instrument for gas production and use units. Main applications: Used for the detection of food grade nitrogen, laboratory testing of high-purity inert gases, and gas quality control in gas production of air separation units. The high sensitivity of the instrument can effectively solve the separation of hydrogen in neon and oxygen in argon.
