AN69: Determination of Aluminum in Complex Matrices Using Chelation Ion Chromatography
DescriptionDetermination of trace metals in complex matrices has been a difficult analytical challenge. This application note describes the extension of Chelation ion chromatography for the analytical determination of aluminum in complex matrices. This technique allows aluminum to be preconcentrated from matrices high in salts, acids, or bases. Following selective concentration, aluminum is eluted to a conventional cation exchange column for separation from other transition metals. Selective detection is accomplished using post-column derivatization with Tiron and subsequent UV detection at 310 nm.
