建立了顶空毛细管气相色谱法测定多西他赛中的甲醇、丙酮、二氯甲烷、正己烷、乙酸乙酯、THF、正庚烷与吡啶。采用DB-624毛细管色谱柱,FID检测器检测。上述8种有机溶剂的回收率为99.3%~103.5%,RSD均小于2.4%。
Headspace capillary gas chromatography was established for the determination of methanol, acetone, methylene chloride, n-hexane, ethyl acetate, THF, n-heptane and pyridine in docetaxel. Using DB-624 capillary column, FID detector detection. The recoveries of these eight organic solvents ranged from 99.3% to 103.5% with RSDs less than 2.4%.
