Trace impurities in high-purity cadmium were determined by high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). 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 excess HCl and cadmium were evaluated. The optimum conditions for the determination were tested in this experiment and discussed. The detection limits ranged from 0.01 to 0.27 µg g-1, depending on the elements. The results for the determination of 22 trace elements in high-purity cadmium are presented.
