本文采用内标法，以丙二醇为内标物，应用上分１００２型气相层析仪测定羟乙基淀粉代血浆中残留甲醇和乙醇的含量。选用天津试剂二厂弹性石英交联聚乙二醇—２０Ｍ毛细管色谱柱，以氢火焰离子化检测器检测，氮气为载体，分流进样．当甲醇和丙二醇内标物浓度比为０．０２：１～０．３２：１，乙二醇和丙二醇内标物浓度比为１．０：１～４．０：１时，被测物质峰面积与浓度呈线性关系，测定了甲醇和乙二醇的相对定量校正因子．甲醇平均测定回收率为９８．７９％，相对标准偏差ＣＶ＝０．０１３％，乙二醇的平均回收率为９７．７７％，ＣＶ＝０．０１１％．
In this paper, internal standard method, propylene glycol as the internal standard, the application on the sub-1002 gas chromatography determination of hydroxyethyl starch on behalf of the residual methanol and ethanol content. Select Tianjin Reagent Factory flexible quartz cross-linked polyethylene glycol -20M capillary column to detect hydrogen flame ionization detector, nitrogen carrier, shunt injection. When the internal standard concentration ratio of methanol and propylene glycol is 0.02: 1 ~ 0.32: 1, the internal standard concentration of ethylene glycol and propylene glycol is 1.0: 1 ~ 4.0: 1, And the concentration of a linear relationship between the determination of methanol and ethylene glycol relative quantitative correction factor. The average recovery of methanol was 98.79%, the relative standard deviation of CV was 0.013%, the average recovery rate of ethylene glycol was 97.77%, CV = 0.011%.
