Brooks and Ahrens (82) determined noble metals in silicate rocks by using ion exchange resins to remove the dissolved precious metals from solution. The solutions were evaporated to dryness and the residue collected in a sodium chloride matrix, which was analyzed qualitatively by spectrograph. They suggested that this procedure could be made quantitative. Miyamoto (83), in 1961, used a gold-silver alloy bead from fire assaying for the spectrographic determination of platinum and palladium in ores.

Place a rod in the steel b l o c k , and then cover with a shallow tray made of folded aluminum foil to prevent loss of the bead if it should roll off the electrode during mounting. Prick 4 h o l e s , roughly V 3 2 in. deep and e v e n l y s p a c e d , in the top of the electrode with the center punch. Place and center the lead bead on the electrode with forceps. 1. 2. cover the end of the electrode uniformly. Force into the holes enough lead to secure the bead firmly to the electrode. With a little practice, this technique b e c o m e s easy and the bead can be formed into a circular sheet just covering the electrode, but not extending beyond the rim.

Pairs of lines of the same type and same intensity under selected excitation conditions) and hence a correction for variation in discharge conditions. 02% for platinum and palladium. The accuracy obtained in determining these elements in the ore was estimated to be ± 1 0 % . When Seath and Beamish (61) were unable to obtain satisfactory results with de Lazlo's method of estimating concentrations from platinum spark lines, they prepared standards by evaporating platinum metal solutions in small lead trays and cupelling them to obtain silver or gold beads.
