摘要 目的建立以毛细管气相色谱法测定盐酸司维拉姆原料药中乙醇、异丙醇和环氧氯丙烷(ECH)3种有机溶剂残留量的方法。方法采用DB-624(30.0 m×0.32 mm,1.8μm)毛细管柱,载气为氮气,采用氢火焰离子化检测器(FID),进样口温度为180℃,检测器温度为220℃,柱温采用程序升温,进样量1μL。结果乙醇、异丙醇和ECH均能得到较好的分离,呈现良好的线性关系,平均回收率分别为101.8%,101.3%,103.9%。结论本方法简便快速,准确性好,灵敏度高,可用于盐酸司维拉姆原料药中残留溶剂的测定。 OBJECTIVE To establish a capillary GC method for the determination of residual organic solvents including alcohol, isopropanol, epichlorohydrin(ECH) in sevelamer hydrochloride drug substance. METHODS This method utilized an Agilent DB-624 GC column, helium as carrier gas. FID was used as detector with the temperature of 220 ℃, and the inlet temperature was 180 ℃. This method used temperature program. The injection volume was 1 μL. RESULTS The three residual organic solvents alcohol, isopropanol, ECH were completely separated, the linear relationship was good, and the average recoveries were 101.8%, 101.3%, 103.9%, respectively. CONCLUSION This method is simple, rapid, accurate and highly sensitive, which can be used for the determination of the residual organic solvents in sevelamer hydrochloride drug substance.
