摘要： The invention provides a method and system for analyzing a gas for the presence of a reactant compound via reaction of primary ions of a specific type. A source gas is introduced to a reaction chamber and ionized in this chamber. The pressure in the reaction chamber is adjusted to avoid the formation of protonated species and other impurities. The primary ions generated in the reaction chamber are transferred to a drift tube. The gas to be analyzed is diluted with a carrier gas and the resulting mixture is introduced into the drift tube. The ionization energy of the carrier gas is equal to or higher than the ionization energy of the primary ions. The product ions resulting in the drift tube from a reaction of the primary ions with the reactant present in the gas to be analyzed are then detected, for example using a mass spectrometer. Preferably, an existing PTR-MS setup is used to perform the method of the present invention.
