Detection power of atomic spectrometry detectors can be substantially improved employing generation of volatile species (VG) of elements since separation from the sample matrix and high efficiency analyte transfer from sample to spectrometer are involved. In addition, VSG makes analyte preconcentration easy. All these factors result in a superior sensitivity. VG is therefore ideally suited for trace and ultratrace elemental/speciation analysis. This course overviews fundamentals, recent developments and perspectives of VSG to trace and ultratrace elemental analysis employing atomic spectrometry detectors.
