Abstract
A gas monitoring system is disclosed. The gas monitoring system may have a first electrode in fluid communication with a first gas and a second gas, and a second electrode spaced apart from the first electrode to contain the second gas between the first and second electrodes. The gas monitoring system may also have a pulse generator configured to apply a series of voltage pulses to the first and second electrodes and create a plasma in the second gas. Each voltage pulse in the series of voltage pulses may have an incrementally higher voltage amplitude than a preceding voltage pulse in the series of voltage pulses. The gas monitoring system may further have a detection controller in communication with the pulse generator. The detection controller may be configured to detect breakdown of the second gas during application of one of the series of voltage pulses, and based on a voltage amplitude of the one of the series of voltage pulses, determine a parameter of the first gas.
