Isotope dilution/inductively coupled plasma mass spectrometry (ID-ICPMS) was applied to determine trace levels of silver in high purity copper. In this experiment, mass discrimination effects by two main components, copper as a matrix and tellurium used for coprecipitation, on the measurments of isotope ratio (107Ag/109Ag) were not significant in ICP-MS. The analytical results for NIST SRMs by ID-ICPMS agreed well with the certified values and those obtained by standard addition using ICP-MS. After concentrating silver by the coprecipitation method, ID-ICPMS can determine a trace level of silver at 0.106 μg g-1 in copper with 3.8% RSD.
