| Abstract: | Trace elements in geological samples were extensively determined by inductively coupled plasma-mass spectrometry(ICP-MS).35 trace elements in USGS reference material samples were analyzed by pressurized acid digestion with Rh single-elemental solution as internal standard and matrix-matching mixed solutions as an external standard calibration solution for long time.The results suggest that relative differences between this study and reference values in concentration of trace elements are less than 10%,and most of them less than 5%. |
