Abstract

This lecture will report on several ways of tackling analytical problems that have been put to use in our laboratory over the past two years. Firstly, several attempts will be described to introduce into the ICP the sample via a commercial electrothermal atomizer so that a transient analytical emission could be obtained with a few microliters of solution. When the emission is analyzed by a quantometer a simultaneous analysis is, in principle, possible. With a carbon rod as atomizer and a ICP emission quantometer (ARL-34000) measurements were performed on Cu, Ag, Pb, Cd and Al in diluted blood samples. In addition the introduction of the sample vapour into the plasma via a conventional graphite cuvette (Perkin-Elmer HGA 500) has been characterized for some of these elements. Secondly, a modified carbon rod was used either as a vapour cell for conventional fluorescence measurements excited by the plasma source either as a resonance monochromator with the consequent advantage of spectral resolution. Detection limits obtained with both methods will be presented together with several practical applications.
