DI-IRMS
Mass spectrometry where purified gas obtained from a sample is alternated rapidly with a standard gas (of known isotopic composition) by means of a system of valves, so that a number of comparative measurements are made of both gases. The relative abundance of isotopes in a sample is then determined.
