Abstract

By arcing a 10-mg fire assay bead at 7 A on a Cu cathode, bead ejection is avoided without buffering. Sensitivities for the precious metals are in the range 0.01 to 0.5 μg and precisions between 8 and 18%. The technique is suitable for rapid screening of fire assay beads for the precious metals.
