在临床药学中,血药浓度的测定,往往要进行萃取分离。由于血液用量少,加上萃取过程中极易出现乳化现象,给被测成分的分离带来一定困难。在实践中,我们用试管代替分液漏斗进行药物萃取,取得较好效果,现介绍如下: In clinical pharmacy, determination of blood drug concentration often requires extraction and separation. Due to the small amount of blood and the emulsification phenomenon in the extraction process, it is difficult to separate the measured components. In practice, we used a test tube instead of a separatory funnel for drug extraction and achieved better results. The following are introduced:
