Absorbance Spectra

A wavelength-modulated continuum source atomic absorption spectrometer is used to obtain time-resolved atomic absorption spectra (absorbance vs wavelength) using an electrothermal atomizer. Absorbance spectra are acquired at a rate of 56 Hz during atomization. The operator may choose any portion of the atomization time period to be examined as well as the number of absorbance profiles to be averaged. This time-resolved spectral information facilitates the positive identification of spectral interferences as well as providing for detailed inspection of both analyte and background absorption signals. Several interferences are examined.

Present Meeting

The collaboration between the University of Bonn and Imperial College on the use of synchrotron radiation for the observation of atomic absorption spectra has yielded much new data since IAU Colloquium No.27 (see also E. Radtke's paper in the present meeting). Among recently observed spectra are those of Tl I, In I, Ga I, Pb I, Sn I and Ge I, while earlier data on Zn I and Cd I have been extended to include double excitations. The first evidence of strong mixing between the d-np channel and double excitations at the same energy has come for Tl I where some of the expected d-np series are absent and, instead, other additional series appear.
