Abstract

The present invention discloses an in vitro method to identify a contaminant gas in a specimen comprising a mixture of gases as a function of the decay rate of at least one species of positronium. The positronium is obtained by directing the positrons from a positron source in to a vessel that contains a specimen containing the mixture of gases comprising a contaminant gas to be identified.
