Graphite furnace atomic absorption

2013-2-15  Graphite furnace AAS shows great precision and excellent correlation to the widely used Hb assay, which is considered to be the “gold standard” for ICH volume determination so far. In contrast to the Hb assay, graphite furnace AAS can also be used for blood volume assessment if other spectophotometrically active substances, such as EB, are applied to the same samples.

Atomization Efficiency of Graphite Furnace in

2018-6-3  Abstract. Abstract. The atomization efficiency of the Hitachi GA-3 graphite furnace for the production and containment of atomic vapour was determined for Ag, Cd, Cr, Ge and In by a method suggested. The method is based on the measurements of residence time, peak hight and peak, area absorbances of analyte atoms.
