Simultaneous determination of hydride- and non-hydride-forming elements by inductively coupled plasma optical emission spectrometry

This report surveys the historical development of dual-mode sample-introduction systems used with inductively coupled plasma optical emission spectrometry for the simultaneous determination of hydride- and non-hydride-forming elements by means of chemical hydride generation (HG) and pneumatic nebulization (PN), respectively. We highlight various aspects of this multi-element analysis approach, including the design of systems for simultaneous HG and PN, selection of (compromised) working conditions and their effect on analytical figures of merit, and applications to the analysis of real samples. We also highlight spectral and non-spectral interferences encountered during such operations.Peer reviewed: YesNRC publication: Ye
