The analytical performance of two inductively coupled plasma optical emission spectrometers with axially and radially viewed configurations, equipped with charge coupled device solid-state detectors was evaluated using Ar, Ba, Mg, and Ni as test elements. Both instruments have similar Echelle optical arrangements and radio-frequency generators, differing only in the viewing mode and in the diameter of the central injector tube, i.e. 2.3 for the axially and 1.4 mm for the radially viewed ICP. The figures of merit evaluated were: warm-up time, short- and long-term stabilities, UV and VIS spectral resolution and limit of detection (LOD) for Ni in 0.14 mol l-1 HNO3 and 1000 mg l-1 Cr media, respectively. The influence of residual carbon content on background equivalent concentration (BEC) and sensitivity attained for Al, As, Ca, Cd, Co, Cr, Cu, Fe, Mg, Mn, Se and Zn was also investigated in both viewing modes. The robustness, short- and long-term stabilities, and UV and VIS spectral resolutions were similar for both configurations. For the radially viewed equipment, the warm-up time was at least a factor of 2 shorter than that for the axially viewed configuration. On the other hand, the sensitivity attained for Ni with the axially viewed arrangement was approximately 20 times better than that with the radially viewed. In both viewing modes, and for most of the evaluated elements, the values of BEC and LOD were similar for all studied carbon concentrations (from 10 to 10 000 mg l-1 C) when working with robust plasma conditions. The Mg II/Mg I ratio at an applied power of 1.3 kW and a nebulizer gas flow-rate of 0.90 and 0.70 l min-1 for axially and radially viewed configurations were 10.6 and 13.7, respectively. Quantitative determinations were successfully performed using both systems.
