Abstract
A microcavity hollow cathode discharge emission source has been design ed and evaluated for ultratrace analysis of sub-muL samples of solutio n residues. It was found that sample drying time and cathode precondit ion had a significant effect on the signal-to-background and signal-to -noise ratios. Detection limits for Cu and Pb were determined to be 10 pg and 210 fg, respectively.
