A metallic furnace atomizer in hydride generation atomic absorption spectrometry: Determination of bismuth and selenium
A flow injection hydride generation system with a metal furnace atomizer (Inconel 600® alloy) was employed for Bi and Se determination. The presented methods have linear ranges up to 200 and 500 μg L- 1 for Bi and Se, respectively, with good linearities (r2 = 0.9997 and 0.9974, respectively). The li...
