Selenium uptake of the cells was assessed by measuring selenium levels in the supernatants (extracellular) and lysates (intracellular) by GFAAS
Al-Saleh and Coate  analyzed Pb in 20 henna products obtained from the local herbalist in the Riadh market in Saudi Arabia by GFAAS
Data obtained in GFAAS
analysis of calcium, iron, magnesium and zinc levels, as well as SOD activity, GSH-PX activity and GSH concentration, were evaluated using Dunnett-t multiple comparison test.
After collection, chemical analysis of each collected eluate of heavy metals (Cd, Pb, Cr, Ni, Zn, Cu) leached from (bio)char using leaching test was measured with FAAS or GFAAS

measurements are often subject to significant interference from light scattering and molecular absorption by matrix components, but this can be adequately corrected using various approaches, including the use of matrix modifiers.
is a simple, cost-effective method for analysis of metals in food matrices.
Afterwards extracts were collected by filtration through filter paper and analysed for Pb, Cd, Zn, Cu, K, Mg concentrations by FAAS or GFAAS
Determination of selenium by GFAAS
in slurries of fish feces to estimate the bioavailability of this micronutrient in feed used in pisciculture.
The Cu concentration in each extract was determined by GFAAS
and the Zn concentration by FAAS.
Determination of selenium in human serum by GFAAS
with transverse heated graphite atomizer and longitudinal zeeman effect background correction.
The elements were quantified by Atomic Absorption Spectrometry both FAAS and GFAAS
