H. Kola et P. Peramaki, Use of parameter-related internal standard method for the determination ofnickel in samples with high salt and acid content by sequential ICP-OES, ATOM SPECT, 20(4), 1999, pp. 142-148
The use of PRISM (Parameter-Related Internal Standard Method) with sequenti
al inductively coupled plasma optical emission spectrometer (ICP-OES) was i
nvestigated. Nickel concentration vias determined in samples with high salt
and acid content. The results obtained with PRISM were compared with data
without any correction, the il:results were obtained by updating the calibr
ation and using yttrium as an internal standard. The quality of the analyti
cal results was markedly improved by using PRISM.
