A new method of dispersive liquid phase microextraction (DLPME) combined with graphite furnace atomic absorption spectrometry (GFAAS) was proposed for the
extremely low analyte concentrations combined with high matrix levels. Graphite furnace atomic absorption spectrophotometry (GFAAS) has been one of the more reliable techniques used for many years and is therefore the pre ferred analytical method. The use of longitudinal Zeeman background correction and the use of matrix modifiers provides accurate results and low detection limits in
Separate vaporization of samples in a graphite furnace was combined to a flame atomic absorption spectrophotometer for metal specific detection of the evolved species. The internal temperature of
