Determination of Trace Elements in Water by On-Line Chelation Preconcentration and Inductively Coupled Plasma- Mass Spectrometry. Weck Laboratories has developed all three sample pre- treatment options within the method which employ co- precipitation, reduction or ion exchange pre- concentration. These steps remove the saline matrix which significantly reduces interferences and enhances the detection limits.
