ABSTRACT:
A discharge ionization detector has a detector body with first and second chambers and an interconnecting aperture passageway. A glow discharge emission in the first chamber is directed through the aperture to cause ionization of column effluent species in the second chamber. A polarizing electrode creates an electric field to cause acceleration of ionized species toward a collector electrode coupled to an electrometer. The detector body is of an electrically-conductive material and is coupled to ground potential to reduce entry of glow discharge-produced electrons into the second chamber.
