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.
Claims10
A method for measuring a total concentration of carbon monoxide and/or hydrocarbons in an oxygen stream to be examined by ion mobility spectrometry, comprising the following steps:
- (a) converting any carbon monoxide and hydrocarbons present in the oxygen stream to carbon dioxide;
- (b) measuring a concentration of carbon dioxide in the oxygen stream after converting step a);
- and
- (c) deducing from measuring step b) the total initial concentration of carbon monoxide and/or hydrocarbons in the oxygen stream.
