    Abstract: A micro plasma sensor system having a glow discharge gap formed by electrodes (53). A fluid to be sensed may be brought into the vicinity of a discharge (56) at the gap. Light from the discharge may be coupled to a spectrum analyzer and/or processor (24) for determining properties of the fluid. A coupling may include a waveguide (63) proximate to the discharge gap. Window cleanliness and electrode electrical isolation may be maintained by the discharge. The optical analyzer may have filters (22) for one or more optical channels to detectors (23). The detectors may output electrical signals to be processed. The electrodes (53) have the ligth waveguide (63) between them. Or the electrodes (53) is formed concentrically around the light waveguide (63) forming an annular discharge gap whit the other electrode. The waveguide (63) may be one or more optical fibers.
