Abstract
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.
