ABSTRACT:
The analytical system for measuring the concentrations of elemental or molecular constituents of an existing solid, liquid or aerosol sample, the sample being dried by an electrothermal atomizer, reduced to ashes, if necessary, vaporized, the sample vapor ionized, the resulting ions supplied during a short time in comparison with the storage time to a preferably simultaneously operating mass spectrometer, and the frequency of the respective ion masses being measured.
