摘 要:目的 建立顶空-气相色谱法测定硫酸长春地辛中残留溶剂甲醇、乙醇、丙酮、二氯甲烷、三氯甲烷、四氢呋喃含量的方法。方法 采用聚乙二醇毛细管柱(DB-WAX),以FID为检测器,柱初始温度45℃保持10 min后升温至220℃,载气为氮气,流速为1.0 ml/min。结果 甲醇在60-360μg/ml范围内,线性关系良好(r=0.9997),平均回收率为98.00%,RSD为1.30%;乙醇在100-600μg/ml范围内,线性关系良好(r=0.9997),平均回收率为99.44%,RSD为1.67%;丙酮在100-600μg/ml范围内,线性关系良好(r=0.9999),平均回收率为97.31%,RSD为2.23%;二氯甲烷在12-72μg/ml范围内,线性关系良好(r=0.9989),平均回收率为97.05%,RSD为2.59%;三氯甲烷在1-8μg/ml范围内,线性关系良好(r=0.9978),平均回收率为99.17%,RSD为4.62%;四氢呋喃在15-90μg/ml浓度范围内,浓度与峰面积呈现良好的线性关系(r=0.9998),平均回收率为95.19%,RSD为2.00%。结论 本法简便,准确度好,灵敏度高,可用于硫酸长春地辛中残留溶剂的含量测定。Objective To establish the method of headspace gas chromatography determinating the residual solvents content in vindesine sulfate such as methanol,ethanol,acetone,methylene chloride,chloroform,tetrahydrofuran. Methods Polyethylene glycol capillary column(DB-WAX) was used and FID was used as detector.The column temperature was enhanced to 220℃ after keeping the column initial temperature at 45℃ for 10 min.Nitrogen was used as carrier gas and its flow velocity was 1.0 ml/min. Results The linear relationship was good in the range from 60 μg/ml to 360 μg/ml(r=0.9997),average recovery rate was 98.00% and RSD was 1.30%.The linear relationship was good in the range from 100 μg/ml to600 μg/ml for ethanol(r=0.9997),average recovery rate was 99.44% and RSD was 1.67%.The linear relationship was good in the range from 100 μg/ml to 600 μg/ml for acetone(r=0.9999),average recovery rate was 97.31% and RSD was2.23%.The linear relationship was good in the range from 12 μg/ml to 72 μg/ml for methylene chloride(r=0.9989),average recovery rate was 97.05% and RSD was 2.59%.The linear relationship was good in the range from 1 μg/ml to 8 μg/ml for chloroform(r=0.9978),average recovery rate was 99.17% and RSD was 4.62%.The linear relationship was good in the range from 15 μg/ml to 90 μg/ml(r=0.9998),average recovery rate was 95.19% and RSD was 2.00%. Conclusion This method is simple and has good accuracy and high sensitivity,which can be used for determination the residual solvents content in vindesine sulfate.
