Biological applications of the carbon rod atomizer in atomic absorption spectroscopy. 1. Preliminary studies on magnesium, iron, copper, lead, and zinc in blood and plasma.

A new technique in atomic absorption spectroscopy is described, which replaces the use of a flame. Samples are injected into a cavity drilled transversely through a carbon rod, and subsequently dried, ashed, and atomized by the application of electric current. The resulting brief absorption signal is recorded and compared with standards. The procedure is… CONTINUE READING
