ABSTRACT:
A counter flowing positive ion-negative ion neutralization chromatograph for analyzing gas samples containing helium and a species which forms negative ions. Two helium resonance lamps are mounted in a chamber with their windows in opposition. The lamps have an emission at 584A and the windows are partially transparent to radiation at 584A. An electrical field is maintained between the lamps. Positive and negative ion sheaths are formed respectively on the outer surface of the two aluminum windows. Because of the electric field, the sheaths move toward opposite windows. The interaction of the ions in the sheaths and impact with the aluminum windows provide information whereby optical and electrical measurements may be made.
