最近看文献的时候,注意了一下人家试验材料是怎么前处理的,发现了有些文献在处理的时候是先研磨,然后称取一定样品加入提取液进行提取。
比如以下文字:
For metabolite extraction, plant material was grinded with mortar and pestle in liquid nitrogen. Metabolites were extracted from the samples (ca. 10 mg) in the 1 mL of
extraction mixture.
液氮研磨都知道怎么做了,快速呱呱呱呱磨成泛白细粉。后面怎么称取呢?样品很容易吸潮的啊。
