STRIPPING ANALYSIS COMBINED ONLINE WITH INDUCTIVELY-COUPLED PLASMA-ATOMIC EMISSION-SPECTROMETRY AND WITH INDUCTIVELY-COUPLED PLASMA-MASS SPECTROMETRY

This review article describes the basic principles of combining stripp ing analysis (SA) on-line with inductively coupled plasma-atomic emiss ion spectrometry (ICP-AES) and with inductively coupled plasma-mass sp ectrometry (ICP-MS). Four applications are reviewed to demonstrate the utility and versatility of the combination of SA with ICP-AES or ICP- MS: (1) preconcentration of an analyte for enhanced sensitivity, (2) e limination of detrimental ICP-AES or ICP-MS matrix effects, (3) elemen tal speciation at trace levels, and (4) sensitive multielement determi nation. Factors influencing the analytical performance of the on-line coupling of SA with ICP-AES or with ICP-MS are also discussed.
