Tóm tắt

The concentrations of 25 trace elements have been determined in 15 international standard rock samples by isotope‐dilution spark source mass spectrometry (ID‐SSMS). This technique yields reliable data down to the ppb concentration range. The agreement between most of our data and recommended values is within 10%. However, for reference samples with low trace element contents (BIR‐1, NIM‐N, PCC‐1, DTS‐1), differences between our data and the literature can be as large as a factor of 80.
