Abstract
Properties, such as concentrations, of gas phase bases or acids of a gas sample are determined by providing a sample gas flow, which includes the bases or acids to be determined as sample constituents, as well as also interfering constituents, which are other constituents than the sample constituents. Reagent ions are provided and introduced into the sample gas flow to arrange proton transfer reaction and thereby forming sample ions. Also a dopant is introduced into the sample gas flow to arrange proton transfer reaction between the dopant and the interfering ions thereby forming dopant ions and electrically neutral interfering constituents. For determination the gas flow with the sample ions to be determined is introduced together with the dopant ions to a mass spectrometer in order to determine the properties of the gas phase bases or acids.
