Abstract

Atomic absorption measurements were used to determine the relative number densities of both zinc atoms and ions in an inductively coupled plasma (ICP). Variations in the absorbance obtained with the zinc atomic and ionic resonance lines reflect the dynamic equilibrium between the number of atoms and ions in the plasma. Absorbance changes as a function of the carrier gas flow-rate were investigated at several incident power values. Ionization is drastically reduced at higher carrier gas flow-rates. Measurements at different observation heights were carried out with widely differing flow-rates of the carrier gas. The results obtained for the tail plume zone are different from those for other zones of the ICP. The characteristics of the ICP using argon-nitrogen mixed gas instead of argon alone were also examined by atomic absorption spectrometry.
