The analytical performance of an unenclosed tungsten coil atomizer operating in Ar-H, (9O:lO) was assessed by electrothermal atomic absorption spectrometry (ETAAS) for the determination of pg to ng levels of Cd, Co, Cr, Mn, Ni and Pb in liquid samples. A three-steps low power unit provided the heati
