锶、钕、铅同位素样品准备方法介绍

针对同位素样品粉末化过程中易受污染的特点，详细介绍了夏威夷大学同位素实验室所使用的方法，包括样品的选取、切割、粗碎、净化、挑选以及粉末化过程。该方法的优点是尽可能地保证样品在粉碎过程中不受外界物质的污染，并去除一些蚀变及氧化物的影响。

The preparation of strontium, neodymium and lead isotopic samples

As the Sr, Nd and Pb isotopic samples are likely to be contaminated during the process of powdering, the method adopted by the Isotopic Laboratory at the University of Hawaii is introduced in detail. The process consists of choice and cut of samples, coarse fracturing, cleaning, picking up and powdering. With this method, the contamination by other materials can be reduced to the minimum, and the advert effects of some alterations and oxides can be eliminated.
