Atomic Flurescence Spectroscopy - Analytical Curiosity or Useful Tool?

Synopsis

Synopsis

Atomic Fluorescence Spectrometry (AFS) is an ideal detection technique for speciation studies concerning hydride forming elements (mainly As, Se and Sb) and Hg. The analytical features of AFS, such as detection limits below the µ/L, allow its application to a great variety of environmental, biological and food samples. AFS represents a suitable alternative to other atomic spectrometers commonly employed in speciation studies such as Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma-Mass Spectrometry (ICPMS). The presentation explains and comments on the instrumental couplings of chromatographic (HPLC and GC) with AFS detection, with online hydride generation for the speciation of inorganic and organic compounds of As, Se and Sb, and cold vapour for Hg. Other optional intermediate steps are online photo-oxidation (UV), pyrolysis for non-directly reducible compounds. Many different sample types (eg water, soils, air, biota, food) have been analysed using these instrumental couplings with AFS detection. These will be summarised and discussed.

The lecture will be preceded by tea/coffee in the Nyholm room and followed by a Mixer in the Nyholm Room.
