电感耦合等离子体质谱法测定辉钼矿中Re、Os含量质量分馏效应的校正

摘要

A liquid which have special 187Re/185Re and 187Os/190Os ratios was prepared using 185Re and 190Os spikes, common rheniumand osmium in molybdenite. This liquid can be used as outer standard to correct the mass bias in the determination of rhenium and osmium in molybdenite by inductively coupled plasma mass spectrometry (ICP-MS).
