ABSTRACT:
Method and apparatus for the thermionic ionization detection of one or more particular constituent components of a sample that is present in a fluid mixture flow provided to a thermionic source. Radiant energy is directed from a radiant energy source to the thermionic source. The radiant energy is sufficient to effect an elevated temperature in the thermionic source. The heated thermionic source causes ionization of the constituent components by means of an ionization process in which electrical charge is transferred from the thermionic source and converted into gas phase ion species. The current of gaseous ions is collected and measured at a collector electrode adjacent to the thermionic source
