Abstract
Aspirin and free salicylic acid were determined in combinations containing caffeine, phenacetin, salicylamide, and acetaminophen by liquid chromatography on poly(methyl methacrylate) resin. Precision and accuracy were +/- 2% for salicylic acid, the latter at levels corresponding to 0.02% of the aspirin content.
摘要
采用聚（甲基丙烯酸甲酯）树脂液相色谱法测定了含有咖啡因、非那西丁、水杨酰胺和对乙酰氨基酚的组合物中的阿司匹林和游离水杨酸。水杨酸的精密度和准确度为±2%，后者对应的水平为阿司匹林含量的0.02%。
