Abstract
A method is provided for the quantitative analysis by ion mobility spectrometry of the concentration of carbon monoxide, methane and higher hydrocarbon species in an oxygen stream. The method includes converting these species present in the oxygen stream into carbon dioxide, measuring the concentration of the carbon dioxide, and deducing from this measurement the initial concentration of the oxidizable species.
