Biological Applications of the Carbon Rod Atomizer in Atomic Absorption Spectroscopy

Abstract 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...

Summary:Abstract 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 particularly suitable for biological work since sample volume requirements are in the submicroliter range. The samples require no pretreatment. The method has given excellent results initially when applied to the measurement of magnesium, iron, copper, lead, and zinc in blood and plasma.
