Abstract

In a previous article, the combination of a sample introduction/desolvation system with a Woodriff type constant temperature furnace atomizer was described. While the performance of the system for the determination of Ag, Cd, Zn, and Pb was characterized by a high sensitivity and reproducibility, utilization of the system described was limited to the determination of easily atomized species due to the relatively low temperatures attainable with the particular furnace employed; also useful lifetime of the graphite furnace components was limited by the desolvator's inability to completely scavenge oxidizing components from the sample. Minor modifications in furnace design allow the analyst to increase the maximum operating temperature, thus expanding the applicability of the particular design while changes in the condenser design significantly increases the desolvation scavenging ability. In this note, the performance, in terms of sensitivity, reproducibility, accuracy, and freedom from simple acid matrix interferances, of this system in the analysis of aqueous samples for Ag, As, Al, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn is documented.
