Trace elements were determined in high purity gold by high resolution inductively coupled plasma mass spectrometry(HR-ICP-MS).Sample were decomposed by aqua regia.To overcome some potentially problematic spectral interference,measurements were acquired in both medium and high resolution modes.The matrix effects due to the presence of excessive HCl and Au were evaluated.The optimum conditions for the determination was tested and discussed.The standard addition method was employed for quantitative analysis.The detection limits range from 0.01 μg/g to 0.28 μg/g depending on the elements.The method is accurate,quick and convenient.It has been applied to the determination of trace elements in high purity gold with satisfactory results.
