超声提取法在固体毒物检材前处理中的作用

Application of the ultr asonic extraction method in solid samples pre-processing for toxicology anal -ysis

针对实际办案中检材中毒物含量很低时不易检验的问题进行了研究,探索出一种固体检材前处理的超声提取法,能够很好地解决这一问题。本方法具有操作简单,检材用量小,提取效果好、省时省费用的优点。

We developed a new method for solid samples extracting,that is the ultrasonic extraction method.It provides the ad-vantage of easily operating,little consumption of samples,high rate of recovery,and low impurity disturbing.
