Gfaa chemistry
WebFor GFAA or ICP-MS analysis, the resultant digestate is reduced in volume while heating and then diluted to a final volume of 100 mL. 2.3 . For ICP-AES or FLAA analyses, hydrochloric acid (HCl) is added to the initial digestate and the sample is refluxed. In an optional step to increase the solubility of some metals

WebGraphite furnace atomic absorption spectrometry (GFAAS) is also known as electrothermal atomic absorption spectrometry (ETAAS). GFAAS is an established technology for quantifying elements at trace and ultra-trace levels (down to low μg/L) while using only small sample volumes (usually less than 100 μL).
