Argon analysis in oxygen mixture using TCD detector with nitrogen carrier
Abstract
Gas chromatography (GC) plays the most important role in chemical analysis, especially in oil and gas composition analysis. There were some methods to analyse the composition of non-hydrocarbon such as CO2, CO, N2, He, H2, O2, Ar... using GC with a Thermal Conductivity Detector (TCD). With the samples containing both argon and oxygen, the detection of them can be inaccurate. In the studies, an acceptable method for the analysis of argon and oxygen is successfully developed based on a GC with TCD detector and nitrogen (N2) as carrier gas. This is the fi rst time the method of analysing Ar content in GC using TCD dectector with N2 as carrier is discussed in a study in Vietnam.
