The analytical calibration in atomic spectrometry similar to other indirect analytical methods has been for many years basically a routine procedure. While the calibration is based on the use of the solution standards, it is only a chemometrical rout

The evaporation as a part of the spectrochemical excitation process is a complicated procedure during which different thermo-chemical reactions connected mainly to the formation of carbides are overshot. This one is accelerated namely at the 4000 K o
