Analytical figures of merit for trace elements in gold, platinum, silver, and sterling silver alloys have been evaluated using radio frequency glow discharge atomic emission spectrometry (rf-GD-AES). Results presented here illustrate rapid plasma stabilizationtimes (< 1 min), short-termprecision of < 1%RSD, and longterm stability of
