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... |
