摘要
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.
