摘 要:[目的]建立药品中环氧氯丙烷有机残留大体积进样、程序升温气化、气相色谱测定方法。[方法]取一定量样品,加入二硫化碳溶液萃取后大体积进样(30μl),经程序升温气化进样-气相色谱测定,进行定量测定。[结果]在上述条件下.该方法的检出限为0.00015%.日内精密度为6.28%~7.81%,日间精密度为7.97%~8.94%,回收率为89.3%~96.7%,线性范围0.145-2.360μg/ml,相关系数0.9975。[结论]该方法操作简单、灵敏度高,可以用于药品中环氧氯丙烷残留的测定。[Objective]To establish a PTV-GC(programmed temperature vaporization-gas chromatography) method for the determination of residual epichlorohydrin in drug. [Methods]Epichlorohydrin in drug was extracted by carbon disulfide. The extract was analyzed by GC with a programmable temperature vaporizer in large volume injection(30 μl). [Results]The range of calibration curve was 0. 145-2. 360 μg/ml, with the determination limit of 0. 000 15 %. The recovery of the method was between 89.3 % and 96.7 %, the precision RSD 〈 100%. [Conclusion] The method is easy to operate and with high sensitiveness. It is suitable for determination of residual epichlorohydrin in drug.
