1. An analytical system for analyzing a liquid sample comprisingstructure defining an analysis region having an inlet and an outlet, a spectrometer system disposed in sensing relation to said analysis region,structure defining a sample inlet port, structure connecting said sample inlet port to said inlet of said analysis region,said analysis region including sample excitation apparatus with a pair of spaced metal electrodes, one of said electrodes having an upper surface in spaced juxtaposition to said other electrode and passage structure connected to said inlet of said analysis region, and the other electrode having a lower surface of annular configuration in spaced juxtaposition to said upper surface of said one electrode, said one metal electrode being disposed with said passage structure extending to an outlet port in its said upper surface, said one electrode including structure in said upper surface defining a plurality of channels extending away from said outlet port for discharge of excess quantities of a liquid sample to be analyzed that has been flowed through said passage structure,control structure for flowing a sample to be analyzed from said sample inlet port through said analysis region, andoutput structure responsive to said spectrometer system for providing output data as a function of the liquid sample flowed into said sample excitation apparatus.
