An analytical technique for measuring both total protium (H) and total deuterium (D) in a gas mixture containing H2, D2, and HD has been developed. This technique uses a micro gas chromatograph uGC with two molecular sieve columns. The carrier gas for one column is deuterium and the second column uses protium as the carrier gas. Laboratory tests have shown that when used in this configuration the micro GC can measure both total protium and total deuterium each with a detection and quantification limit of less than 20 ppm. This is a low-cost technology can be used to provide comparable results with the data generated from an expensive mass spectrometry with capabilities of high resolution at low mass.
