ABSTRACT:
An electric discharge tube for a gas emission spectrometer and method for analyzing and measuring low concentration levels of multiple gas/vapor impurities in a gas stream under continuous flow conditions. The electric discharge tube comprises a plurality of analytical sites through which emissive radiation generated by an alternating source of power across the tube can be analyzed and measured.
