摘 要: | 目的:建立测定左西孟旦原料药中6种有机溶剂即甲醇、乙醇、丙酮、二氯甲烷、异丙醇与二氧六环残留量的方法。方法:采用气相色谱法。Agilent HP-5毛细管柱,(5%)苯基-(95%)甲基聚硅氧烷为固定液;柱温采取程序升温;氢火焰离子化检测器温度为250℃;载气为高纯N2;进样口温度为200℃,分流比为10∶1;采用顶空进样法测定,顶空加热温度为100℃,加热时间为40min。结果:甲醇、乙醇、丙酮、二氯甲烷、异丙醇与二氧六环的检测质量浓度线性范围分别为150.1449.5μg/ml(r=0.999 8)、250.6449.5μg/ml(r=0.999 8)、250.6751.2μg/ml(r=0.999 6)、249.8751.2μg/ml(r=0.999 6)、249.8749.9μg/ml(r=0.999 7)、29.09749.9μg/ml(r=0.999 7)、29.0989.68μg/ml(r=0.999 8)、250.289.68μg/ml(r=0.999 8)、250.2750.9μg/ml(r=0.999 6)、18.91750.9μg/ml(r=0.999 6)、18.9157.92μg/ml(r=0.999 7);平均回收率为99.9%57.92μg/ml(r=0.999 7);平均回收率为99.9%100.0%(RSD=0.88%100.0%(RSD=0.88%1.11%,n=3);定量限分别为0.12、0.18、0.33、0.21、0.45、0.99 ng。样品中只检出异丙醇。结论:建立的方法快速简便,结果准确可靠。

Abstract: | OBJECTIVE:To establish the method for the determination of 6 residual organic solvents as methanol,alcohol,acetone,dichlormethane,isopropanol and dioxane in levosimendan raw material.METHODS:Gas chromatography was used.Capillary column(5%)phenyl-(95%)methylpolysiloxane was used as fixation fluid by temperature programming;and the temperature of flame ionization detector was 250 ℃,and high purity N2was used as carrier gas.Inlet temperature was set at 200 ℃ with split ratio of 10 ∶ 1.The conditions of headspace method included heating temperature of 100 ℃ and heating time of 40 min.RESULTS:The linear range of methanol,alcohol,acetone,dichlormethane,isopropanol and dioxane were 150.1-449.5 μg/ml(r=0.999 8),250.6-751.2 μg/ml(r=0.999 6),249.8-749.9 μg/ml(r=0.999 7),29.09-89.68 μg/ml(r=0.999 8),250.2-750.9 μg/ml(r=0.999 6) and 18.91-57.92 μg/ml(r=0.999 7),respectively;average recoveries were 99.9%-100.0%(RSD=0.88%-1.11%,n=3).The limits of quantification were 0.12,0.18,0.33,0.21,0.45 and 0.99 ng.Only the isopropanol was detected in samples.CONCLUSIONS:The established method is rapid,simple,accurate and reliable. |
