	abstract = {The effect of easily ionized element (EIE) matrices on analyte emission, from a parallel plate capacitively coupled plasma (PP-CCP), has been studied. NaCl and NaNO3 were used as typical matrices and the interference on Ag emission was studied as a function of the amount of EIE and applied plasma forward power. Compared with the emission signal without the presence of matrices, the presence of either NaCl or NaNO3 as a concomitant in the sample, causes an interference effect by both enhancing, and decreasing, the emission intensity depending on the amount of added EIE. The maximum signal interference, signal enhancement, was observed at 125 W plasma forward power. The degree of enhancement from an EIE decreases with increasing forward power switching to a signal depression at a forward power of 250 W. (C) 2000 Elsevier Science B.V. All rights reserved.},

	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.},

	abstract = {A survey of spatially resolved electron number density (n(e)) in the tail cone of the inductively coupled argon plasma (ICAP) is presented: all of the results of the survey have been radially inverted by numerical, asymmetric Abel inversion. The survey extends over the entire volume of the plasma beyond the exit of the ICAP torch; It extends over distances of z = 5-25 mm downstream from the induction coil, and over radial distances of +/- 8 mm from the discharge axis. The survey also explores a range of inner argon flow rates (Q(IN)), solvent plasma load (Q(SPL)) and r.f. power: moreover, it explores loading by water, methanol and chloroform. Throughout the survey, n(e) was determined from the intensity of one, optically thin argon line, by a method which assumes that the atomic state distribution function (ASDF) for argon lies close to local thermal equilibrium (LTE). The validity of this assumption is reviewed. Also examined are the discrepancies between n(e) from this method and n(e) from Stark broadening measurements. With the error taken into account, the results of the survey reveal how time averaged values of n(e) in the ICAP respond over an extensive, previously unexplored range of experimental parameters. Moreover, the spatial information lends insight into how the thermal conditions and the transport of energy respond. Overall, the response may be described in terms of energy consumption along the axial channel and thermal pinch within the induction region. The predominating effect depends on the solvent plasma load, the solvent composition, the robustness of the discharge, and the distribution of solvent material over the argon stream.},
