Separation and Determination of Argon and Oxygen in High-purity Nitrogen Streams by Gas Chromatography

Abstract

THE analysis of high-purity nitrogen streams derived from air separation plants is usually limited to quantitative measurement of the oxygen content, often using a Hersch oxygen meter1. Argon, which may be found in various concentrations, depending on the design of the air separation plant, cannot be analysed on these meters.
