Abstract
A sensitive and convenient electron-capture gas chromatographic procedure for analysis of MHPG in small volumes of urine is described. The method involves acetylation under aqueous conditions, extraction with an organic solvent and reaction with trifluoroacetic anhydride under anhydrous conditions. The resultant derivative is separated and quantitated on a gas chromatograph equipped with a fused silica capillary column and an electron-capture detector.
摘要
本文描述了一种灵敏且便捷的电子捕获气相色谱法，用于分析少量尿液中的3-甲氧基-4-羟基苯乙二醇（MHPG）。该方法包括在水相条件下进行乙酰化反应，用有机溶剂萃取，以及在无水条件下与三氟乙酸酐反应。所得衍生物在配备熔融石英毛细管柱和电子捕获检测器的气相色谱仪上进行分离和定量分析。
