Classification: CPC H | IPC H

Claim 0:
1. An ionization apparatus (10) for ionizing an analyte (S), comprising an inlet (E), an outlet (A), a first electrode (1), a second electrode (2), a dielectric element (3) and a charge carrier filter (20, 21), wherein:
the first electrode (1), the second electrode (2) and the dielectric element (3) are arranged relative to one another such that, by applying an electric voltage between the first electrode (1) and the second electrode (2), a dielectric barrier discharge is establishable in a discharge area (5) in the ionization apparatus (10);
the inlet (E) allows a flow of analyte (S) into the ionization apparatus (10), the discharge area (5) allows a flow of analyte (S) therethrough, and the outlet (A) allows a discharge of the analyte (S) from the ionization apparatus (10);
the charge carrier filter (20, 21) is arranged upstream of the outlet (A) of the ionization apparatus (10) and configured to filter ions or charged particles on the basis of their type of charge; and
wherein a magnetic field is generable (21) by the charge carrier filter (20, 21), or the charge carrier filter (20, 21) is a grid (20).
