论述了用多接收器磁扇形电感耦合等离子体质谱法 (ＭＣ -ＩＣＰＭＳ)精确测定样品与参考标样之间钼同位素组成与质量有关的差别的分析方法。用Ｚｒ或Ｒｕ“元素示踪”来校正仪器质量偏移。利用 1～ 10 μｇ的Ｍｏ ,可测得 95Ｍｏ/ 97Ｍｏ之差精确度为± 0 .2‰。将来自于示踪元
The analytical method for the accurate determination of the differences in molybdenum isotopic composition and quality between a sample and a reference standard using a multi-receiver magnetic sector inductively coupled plasma mass spectrometry (MC-ICPMS) is described. The instrument mass shift was corrected with “tracers” of Zr or Ru. Using 1 ~ 10 μg of Mo, 95Mo / 97Mo difference of ± 0.2% can be measured. Will come from the tracer element
