  • Method for ionizing gaseous samples by means of a dielectric barrier discharge and for subsequently analyzing the produced sample ions in an analysis appliance
    Patent number: 11043368
    Abstract: A method for ionizing gaseous samples by dielectric barrier discharge and for subsequently analyzing the produced sample ions in an analysis appliance, in particular a mass spectrometer or an ion mobility spectrometer, produces the sample ions by a plasma caused by a dielectric barrier discharge, wherein the dielectric barrier discharge is produced by virtue of a plasma gas being supplied through a capillary made of a dielectric material, wherein a wire-shaped electrode is arranged within the capillary, the electrode being connected to an AC voltage source, wherein the gaseous sample is supplied to the exit region of the capillary, wherein the wire-shaped electrode is connected to the AC voltage source on the high-voltage side.
    Type: Grant
