In the first year, the analytical procedures which would enable the ICP-MS to precisely and simultaneously determine about 40 trace elements in rock samples has been established. The procedures includes: (1) digestion of rock samples using distilled HF+HNO3 in screw-top teflon beakers in the clean room, (2) digestion of USGS and other rock standards through the same processes and then using them as calibration references, and (3) using certain internal standards during the measurements to monitor the sensitivity shift of the machine. Consequently, the ICP-MS method developed marks with: (1) simple sample preparation, (2) straightforward data reduction, and (3) high analytical precision, and thus can be applicable to trace element determinations of common rock samples.application/pdf266616 bytesapplication/pdfzh-TW國立臺灣大學地質科學系暨研究所感應耦合電漿質譜術微量元素分析ICP-MSTrace element determinationsreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/11792/1/902116M002013.pdf
