Overcoming the challenges of direct organic elemental analysis with ICP-MS
Jul 27 2011
Author: Erik Buseth on behalf of PerkinElmer
Analysing organic matrices for trace elements is a challenging proposition and frequently involves complex sample preparation steps. This is time consuming and potentially risks introducing contaminants or losing elements of interest. Sample digestion or wet ashing methods result in an aqueous matrix which can then be analysed by conventional ICP-OES or, where superior detection limits are required, by ICP-MS. However, the direct analysis of organic matrices by ICP techniques has historically presented a number of challenges.
