The method further comprises sampling, by a gas flow, the analyte ions mentioned for mass spectrometric analysis, and at least one of the following: (i) removal of charge in said conditioning channel (55); (Ii) coaxial mixing Analytfluss with the flow of conditioned plasma; and (iii) cooling the mixed flow in a sonic or supersonic jet to reduce the region of Penning ionization to cold jet.
