Abstract
The invention relates to a method for detecting gases that can be ionized wherein an atmospheric plasma jet is produced, wherein a gas mixture is brought into interaction with the plasma jet, and wherein an electrical quantity is measured as a measure of the concentration of the gas in the gas mixture. The invention further relates to a device for detecting gases that can be ionized, including a gas inlet, means for ionizing a gas, a voltage source, two electrodes, and means for determining an amperage, wherein the two electrodes are connected to the voltage source, wherein the means for determining an amperage are connected to the electrodes in such a way that the magnitude of the current flowing between the electrodes can be measured, and wherein a plasma nozzle is provided to produce an atmospheric plasma jet.
