Patent number: 10777401Abstract: The present invention relates to the technical field of ionizing a gaseous substance, in particular the ionizing or ionization of a gaseous substance in preparation for its analysis. A device is intended to make a discharge gas and a test substance ionizable in a flow-through mode without essentially destroying or fragmenting the sample substance. In order to avoid a high expenditure in terms of construction and equipment, the device is intended to be usable under ambient conditions and to ensure a high sensitivity in a possible analysis of an ionized substance. To this end, an ionizing device is used for flow-through ionization of a discharge gas and of a sample substance at an absolute pressure of more than 40 kPa in the ionizing device during ionization. The ionizing device comprises an inlet, an outlet, a first electrode, a dielectric element and a second electrode.Type: GrantFiled: December 14, 2016Date of Patent: September 15, 2020Assignee: PLASMION GMBHInventor: Jan-Christoph Wolf
