重量法是我们卫生化学中最为古老的基本分析方法,在现代卫生检测中仍有不可替代的作用。为了减少称重的误差,在重量法检测中我们常会碰到恒重这个问题。工作中发现,在不同的检测项目的分析方法中对恒重操作的描述不尽
Gravimetric method is one of the oldest basic analytical methods in our hygienic chemistry, which still plays an irreplaceable role in modern hygienic testing. In order to reduce the error of weighing, we often encounter the problem of constant weight in gravimetric test. During the work, it was found that the description of constant weight operation in different test items analysis methods
