ONH836-G8 Oxygen Nitrogen Hydrogen Analyzer

Instrument Introduction

ONH836-G8 Oxygen Nitrogen Hydrogen AnalyzerWidely used in fields such as steel, machinery, aerospace, energy, military industry, and university research, it is mainly used for the analysis of oxygen, nitrogen, and hydrogen content in black metals, non-ferrous metals, various alloys, magnetic materials, rare earths, silicon, ceramics, and other metal or non-metal solid inorganic materials.

ONH836-G8 Oxygen Nitrogen Hydrogen AnalyzerUnder the blowing of helium gas (argon gas can be used for single oxygen measurement), the sample is melted in a graphite crucible by high temperature heating. The oxygen in the sample reacts with the carbon in the graphite crucible to generate CO, while nitrogen escapes in the form of nitrogen gas. Then, these mixed gases are sent by helium to the converter, where CO is converted into CO₂Nitrogen does not react. The mixed gas after passing through the converter is further sent to the infrared detection tank, where CO is detected2And H2O has been detected. Finally, the remaining mixed gas is detected through a thermal conductivity detection cell with nitrogen gas.
