However, accurate wet chemical analyses tend to require complex dissolution procedures that normally involve the use of combinations of concentrated acids prior to analysis, for instance by Inductively Coupled Plasma Optical Emission or Mass Spectrometry techniques (ICP-OES/MS).
Wet chemical methods can be complicated, they also dilute the sample by several fold, and may result in the loss of some of the volatile analytes during the dissolution process.
High Resolution Glow-Discharge Mass Spectrometry (GDMS) based on reduced pressure GD ion source operating with flat-cell geometry is an ideally suited analytical technique for complete, precise and accurate element characterizations of powdered/particulate materials.
