Claim:
1. A non-radioactive plasma ion source, comprising: a) a housing, defining b) at least four planar electrodes mounted along the major longitudinal axis of the housing between the counterflow gas outlet and the analyte gas outlet, thereby partitioning the interior volume into at least three chambers, including c) a non-radioactive discharger between two of the planar electrodes, that generates an ionized plasma within the discharger chamber for exposure to the homogenous electric field, whereby a selected ion species is directed by the homogenous electric field into combination with a sample gas that is directed into at least one of the first gas inlet and the second gas inlet, the combination thereby forming analyte ion species of an analyte gas that is discharged through the analyte gas outlet.
