Abstract
The role of metallic matrix modifiers in AAS is considered; for elemen ts reduced, together with modifier elements, during ashing and the beg inning of the atomization process, the thermodynamic activity and melt ing points of the alloys formed are important. For Mg2+, prevention of the effects of halide ions is considered, as is also the behaviour of buffer and/or carrier in emission spectrometric analysis of the other alkali and alkaline earths.
