ABSTRACT:
The invention relates to an ionization detector comprising a discharge section which generates ultraviolet rays and a detector section which collects ionic current caused or altered by the photoionization of a sample gas with the ultraviolet radiation. A container holds the two sections together and a pointed cathode is spaced at least several millimeters from an anode in order that the electric discharge may be executed as field-emission discharge.
