On-line analyte preconcentration with atomic spectrometric detection

Abstract

Pre-concentration of analytes, or matrix removal to overcome interferences using mini- or micro-columns of exchange media prior to atomic spectrometric detection is becoming increasingly more common. This paper is a review of some of the more recent applications of chelating, ion exchange and other resins and gels that have been used to accomplish this. © 1991, Hindawi Publishing Corporation.
