ABSTRACT:
A gaseous target analyte present as a minor constituent in an admixture with at least one other gaseous species can be detected using a cavity enhanced optical spectrometer by a process comprising the steps of:i) identifying a plurality of strong spectral absorption peaks of the target analyte which are present within the scanning range of the spectrometer,ii) determining for the identified peaks the pressure region above which the peak width increases substantially with increasing pressure and below which the peak width is substantially independent of pressure,iii) determining which of the peaks identified in step i) are, within the pressure region determined in step ii), free from spectral interference by any of the other components of the admixture.iv) measuring the spectrum of the admixture at the pressure region identified in step ii).
