The graphite furnace atomic absorption spectrometry (GFAAS) is recommended for small or trace aluminum contents, from 0.01 to 0.1 mg x [L.sup.-1] [7].
Selenium uptake of the cells was assessed by measuring selenium levels in the supernatants (extracellular) and lysates (intracellular) by GFAAS. At each dose, SeMet uptake was highest at 48 h.
The assay method used for the content of manganese, lead, cadmium, and chromium in the samples of enamel and dentin of the retained teeth was Graphite Furnace Atomic Absorption Spectrometry (GFAAS).
GFAAS (Figure 2) uses an electrically heated graphite tube to vaporize and atomize the analyte at temperatures up to 3000[degrees]C before its detection.
For an accurate determination of heavy metal contents in cosmetic products, a variety of analytical techniques have been used for the assessment of metals in cosmetics, such as Laser Induced Breakdown Spectroscopy (LIBS) [17], Inductively Coupled Plasma Mass Spectrometry (ICP-MS) [18], Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) [19], Flame Atomic Absorption Spectrometry (FAAS) [4, 20], and Graphite Furnace Atomic Absorption Spectrometry (GFAAS) [21].
Blood specimens were analyzed for Mn using graphite furnace atomic absorption spectrometry (GFAAS; PerkinElmer[R] model 4100 ZL) equipped with a transversely heated graphite atomizer and a longitudinal Zeeman background correction system (PerkinElmer[R] Life and Analytical Sciences, Shelton, CT) using previously described method and quality-control measures (Praamsma et al.
