等离子体质谱法(ICP/MS)测量天然锇同位素丰度

Determination of Abundance of Natural Osmium by ICP/MS

本文报道ICP／MS测量天然锇同位素的测量方法。作中研究了样品浓度、积分时间、测量次数等对锇同位素丰度测量精度和准确度的影响，测得的同位素丰度与天然丰度一致。测量了锇的记忆效应。

The method of determiniation of natural abundane of Osmium has been developed.The influnces of concentration of osmium,integrated time and measured times on accu Rate and precision of abundances have been measured.The abundances measured are Good agree with natural abundances The memory of osmium in ICP/MS has also been measured.
