本文介绍高效液相法测定乙酰水杨酸片中的非那西丁含量。在柱效不高、咖啡因与非那西(?)不能完全分离时可用峰抑制法排除干扰。使用的柱子为ODSC_(18)10μ40×25cm、流动相为甲醇:水=75:25、检测波长247nm、参比波长289nm。
This article describes the HPLC method for the determination of phenacetin content of acetylsalicylic acid tablets. In the column efficiency is not high, caffeine and phenacetin (?) Can not be completely separated peak suppression method can be used to eliminate interference. The column used was ODSC_ (18) 10μ40 × 25cm, the mobile phase was methanol: water = 75:25, the detection wavelength was 247nm and the reference wavelength was 289nm.
