Abstract (en)
[origin: EP1217643A1] Evaluation of the condition of organisms or natural products which emit substances into the atmosphere comprises determination of one or more of these substances in a gaseous mixture. This is achieved by irradiation with an ion beam under a high vacuum in a mass spectrometer and evaluation of the spectrum produced. Independent claims are included for: (a) a method for analyzing a gaseous mixture containing a main component (concentration not less than 0.1 vol%) and a minor component (concentration not more than 0.1 vol%) by irradiation with an ion beam under a high vacuum in a mass spectrometer and evaluation of the spectrum produced; and (b) apparatus for analyzing a gaseous mixture comprising a mass spectrometer fitted with a gas supply system (1 - 4) in which the sample forms an molecular stream in an intermediate vacuum chamber (24) held under constant vacuum and then, using a pressure gradient across a capillary (10) connected to this, producing a second molecular stream in a high vacuum chamber (22).
