Hydrogen purity analysis. Researchers using a gas chromatograph (GC) analyser during a hydrogen purity analysis. The gas chromatograph separates a gas sample into individual compounds so that they can be separately detected,identified and quantified. Here,it is being used to carry out a hydrogen purity analysis using a hydrogen impurity enrichment device (HIED),a krypton tracer enrichment method.
