开发了一种使用同位素稀释-电感耦合等离子体质谱法测定地质样品（黄铁矿和岩石）中痕量铼的方法。采用Carius管消化法进行样品制备。总程序空白可限制在 1. 4 - 10 pg 范围内。通过分析国标辉钼矿样品对方法进行了验证，结果与标准值（17. 39±0. 32）μg/g吻合较好。该方法用于岩石样品中痕量Re（1.27 ng/g）的测定，精度为3. 89% RSD(n=4, 2s)。
A method for the determination of trace rhenium in geological samples (pyrites and rocks) using isotope dilution-inductively coupled plasma mass spectrometry was developed. Carius tube digestion method was used for sample preparation. The total procedure blanks could be limited in the range of 1. 4 - 10 pg. The method was verified by analyzing the national standard reference molybdenite sample and the result was in good agreement with the certified value (17. 39±0. 32) μg/g. The method has been applied to the determination of trace Re (1.27 ng/g) in rock sample with precision of 3. 89% RSD(n=4, 2s).
