ATOM TRAPPING AND IN SITU PRECONCENTRATION TECHNIQUES FOR FLAME ATOMIC ABSORPTION SPECTROMETRY [Review]

摘要

The historical development of the in situ preconcentration technique in atomic absorption spectrometry based on a conventional flame coupled with an atom trapping tube and collection of the analyte atoms is presented. The current state of the art, including advantages and limitations of this approach, is discussed. (C) 1997 Elsevier Science B.V. [References: 194]
