| Abstract: | A method for the determination of Cr,Ga,In,Te and Tl in geological samples by inductively coupled plasma-mass spectrometry(ICP-MS) was developed.The sample dissolution conditions and instrument measurement parameters were optimized through experiments.The detection limits of the method for these elements were in the range of 0.0013~0.063 μg/g with the precision of 2.00%~4.87%RSD(n=11).The method provides the advantages of high sensitivity and accuracy,simple operation,high efficiency and is suitable for the routine analysis of scattered elements of Cr,Ga,In,Te and Tl in geological samples. |
| Keywords: | inductively coupled plasma-mass spectrometry geological samples scattered element |
