ELECTROTHERMAL VAPORIZATION FOR SIMULTANEOUS MULTIELEMENT DETERMINATION

New techniques have been developed for analysis of microsamples. A mod ification of a graphite furnace for furnace atomization non-thermal ex citation spectrometry (FANES) was used in electrothermal vaporization inductively coupled plasma mass spectrometry. The figures of merit, su ch as the maximum mass which can be introduced into the plasma (25 mu g), the detection limits of a number of elements (Ag: 0.02 pg; Co: 0.3 pg; Mn: 0.2 pg) in concentrated nitrogen acid, the dynamical range of calibration curves and the influence of sodium on analyte signals are investigated and compared to the ones obtained for FANES.
