A glow discharge using a solution as the cathode was investigated to add to the understanding of the
operating mechanism and characteristics of such systems. The intensities and vertical distributions of
emission from several analytes and background species were observed and compared with the vertical
distribution of Fe excitation and OH rotational temperatures, as well as to electrical characteristics. The
effects of the discharge gap size, the pH and conductivity of the solution, the applied current and the
solution flow rate on these distributions were also studied. Detection limits for this system were found to be
comparable to those of similar systems and mostly in range of tens of parts per billion.
