索密痛片、安痛定片和复方乙酰水杨酸片均为复方制剂,每种片剂含3～4种成分,用化学法鉴别,往往要经过用乙醚、氯仿提取分离等步骤,比较麻烦。本文采用气-液色谱法作鉴别,提高了灵敏度和自动化程度,一个样品分析一般10分钟内即可完成。现报告如下:一、气相色谱分析条件1.色谱柱:SE-52(1.5%),为苯基(5%)甲基硅酮,Ghromsorb W,60～80目,酸洗、硅烷化处理。玻璃柱长1.5m,内径3mm。2.鉴定器:氢火焰离子化鉴定器。
Soup pain tablets, analgesic tablets and compound acetylsalicylic acid tablets are compound preparations, each containing 3 to 4 kinds of tablet ingredients, chemical identification, often through the ether, chloroform extraction and separation steps, compared trouble. In this paper, gas-liquid chromatography for identification, improve the degree of sensitivity and automation, a sample analysis can be completed within 10 minutes. The report is as follows: 1. Gas chromatography conditions 1. Column: SE-52 (1.5%), phenyl (5%) methyl silicone, Ghromsorb W, 60 to 80 mesh, pickling, silanization. Glass column length 1.5m, diameter 3mm. 2. Identifier: hydrogen flame ionization detector.
