Accurate and rapid determination of impurity content in high-purity nitrogen
Abstract: The working principle and working conditions of HE50 DID helium ionization discharge chromatograph based on heart cutting and deoxygenation method are introduced. Starting from actual production, WISCO Oxygen Company has improved the gas flow process of the chromatograph. After analysis and testing, a complete set of analysis methods has been established. The measurement results of the impurity content in high-purity nitrogen show that this analysis method can meet the production needs, so as to achieve the purpose of accurately and quickly measuring the impurity content in high-purity nitrogen.
