ABSTRACT:
The invention relates to method of monitoring a gas, which comprises simultaneously flowing said gas through a plurality of means for trapping gaseous species, each of said trapping means being adapted so that its selectivity in trapping of gaseous species differs from such selectivity of the other means in said plurality; subjecting each means of said plurality to conditions effecting release of any gaseous species trapped thereby while maintaining the other means of said plurality in a condition suitable for said selective trapping of gaseous species; contacting the gas issuing from each of said plurality of trapping means with each of a plurality of means for sensing said gaseous species, each said sensing means being adapted so that its selectivity to sensing said gaseous species differs from such selectivity of the other sensing means; and to apparatus for carrying out the method.
