Development of trace enrichment techniques for trace metals in natural waters using high pressure liquid chromatography

Creator:

Ambrose, Arthur Sigurd

Abstract:

An on-line trace enrichment (TE) system, based on high pressure liquid chromatogroaphy (HPLC) and flame atomic absorption (AA), has been developed for trace metal analysis. The sample is pumped through a column filled with a cation exchange resin which traps metal ions. The ions are subsequently stripped from the column...

Development of automated on-line ion exchange systems for the determination of chemical speciation of trace metals in natural waters

Creator:

Liu, Yan

Abstract:

An automated on-line ion exchange trace enrichment system has been developed to improve the detection limits of flame atomic absorption (AA) spectrophotometry in the determination of trace metals in natural waters. The sample solution is passed through a column of Chelex-100 chelating resin by a carrier buffer stream delivered from...
