Tritium Enrichment by Gas Chromatography

Abstract

GAS–SOLID chromatography has proved to be a promising method for enrichment of tritium in hydrogen gas samples1. Previous work has shown that tritium can be enriched with a concentration factor of about 20 in hydrogen samples of up to 300 ml. and with a tritium loss of up to 5 per cent in a relatively small system. Many problems involving low-level tritium determination, however, require much larger samples of hydrogen (or its equivalent as water) to obtain sufficient tritium for detection and it was, therefore, of interest to see how far the gas chromatographic system could be extended in this direction.
