Abstract:

The matrix dependence of analyte excitation in the high-voltage spark discharge has been investigated. The analyte excitation distributions of Fe(I), Mo(I), and Cu(I) have been measured. The large wavelength range of a custom echelle/CCD system was exploited for these determinations. The analyte excitation within the high-voltage spark on a time-integrated basis was determined to be independent of both sample matrix and sampled species.
