Chemical ionization with reactant - ions form with atmospheric pressure in a mass spectrometer

摘要

A method for the chemical ionization of gaseous analyte molecules, characterized in that, in a reduction in pressure to atmospheric pressure, which are held in the combustion chamber by means of a corona - discharge at the taylor - cone of an aqueous liquid hydro present - clusters are formed which, in a temperature-controlled entraining gas discharged from the combustion chamber and outside of the combustion chamber with the analyte molecules are mixed.
