Abstract
A gas monitoring system is disclosed. The gas monitoring system may have a first electrode, a second electrode spaced apart from the first electrode to receive a gas between the first and second electrodes, and a pulse generator configured to apply a voltage pulse, tuned to a particular constituent of the gas, to the first and second electrodes and create a non-thermal plasma between the first and second electrodes. The gas monitoring system may also have a detection controller in communication with the pulse generator. The detection controller may be configured to determine an actual current between the first and second electrodes during application of the voltage pulse, and to determine a concentration of the constituent based on the actual current and an expected identity of the constituent.
