Electrothermal vaporization for simultaneous multi-element determination

Abstract

New techniques have been developed for analysis of microsamples. A modification of a graphite furnace for furnace atomization non-thermal excitation spectrometry (FANES) was used in electrothermal vaporization inductively coupled plasma mass spectrometry. The figures of merit, such as the maximum mass which can be introduced into the plasma (25 µg), 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 of analyte signals are investigated and compared to the ones obtained for FANES.
