	abstract = {The degree of ionization for Mg and Cd vaporized into a parallel plate capacitively coupled plasma (PP-CCP) has been studied. Using electrothermal vaporization and a CCP operating at 200 W, the degree of ionization is 83\% and 48\% for Mg and Cd, respectively. An increase in applied power increases the degree of ionization. Changes in plasma gas flow rate, up to 1.0 l min(-1), also change the degree of ionization slightly, probably due to mass transport effects and slight changes in the discharge conditions. Additions of EIE (Na as NaNO3) up to 10 times (w/w) the analyte increase the degree of ionization slightly.},

	abstract = {Electronic excitation (T-exc) and rotational (T-rot) temperatures were determined for a parallel plate capacitively coupled rf plasma operating at atmospheric pressure. T-exc was calculated from the slope of the Boltzmann plot using Fe and He as the thermometric species and Ph excitation temperature was calculated using the two line method. Over a power range from 100 W to 250 W, excitation temperatures are 3255-3900 K for He, 3540-4500 K for Pb, and 4300-4890 K for Fe. The rotational temperature was measured using both OK and N-2(+) molecular spectra and the values are in the range of 828-911 K and 845-956 K respectively over a power range of 75-275 W. Signal-to-noise ratios, signal-to-background ratios, and absolute detection limit for lead (0.33 ng) and silver (24 pg) are also reported. (C) 1997 Elsevier Science B.V.},
