Analysis of Trace Components in Neon by Gas Chromatography

In order to complete the test of trace concentrations in neon carrier gas of solid tritium breeder system for fusion reactor, it is very necessary to establish a high precision analytical system and develop a method of Gas Chromatography (GC). The GC system was composed of three detectors and five separated columns and other auxiliary systems, meanwhile it has established analysis methods of testing trace He, H2 and impurity components in Ne carrier gas. The results showed that the Relative Standard Deviation (RSD) values of the concentration and peak area of each component were less than 5.0%, and the linear correlation coefficients (R2) were greater than 0.99 with the GC analysis system, which could be used to testing trace concentrations in neon with good repeatability. It could support the requirement of tritium efficiency in the Tritium Analysis and Measurement system (TAMS), besides, it could provide technology data and support for the radiation tritium system.
