目的:建立磺胺多辛原料药中冰醋酸、N,N-二甲基甲酰胺(DMF)有机溶剂残留量的气相色谱测定方法.方法:样品用甲醇溶解后,在DB-WAX毛细管柱(30 m×0.32 mm×0.5μm)上实现分离(FID检测器).结果:2种溶剂残留均达到良好分离,冰醋酸和DMF线性范围分别为Y=3.565 7X+4.078 4(r=0.999 3)、Y=7.248 9X-7.488 9(r=0.999 6),精密度RSD分别为1.8%、3.3%,回收率分别为99.7%、100.1%,检测限分别为35.46ng/mL、66.5 ng/mL.结论:本方法准确、可靠、灵敏度高,适用于磺胺多辛中冰醋酸与N,N-二甲基甲酰胺残留量的检测.

Objective: To establish a method for the determination of residual organic solvent,acetic acid and NN-Dimethylformamide( DMF) in sulfadoxine. Method: Capillary gas chromatographic method was introduced for the determination, residual organic solvent was extracted from sulfadoxine with methanol and separated in DB-WAX capillary column with FID detector. Result: the linear relation of acetic acid and NN-Dimethylformamide was Y = 3. 565 7X + 4. 078 4 ( r = 0. 999 3) and Y = 7. 248 9X - 7. 488 9 ( r = 0. 999 6) ,with accuracy RSD ( 1. 8% and 3. 3%) ,recovery rate ( 99. 7% and 100. 1%) ,LOD ( 35. 46 ng /mL and 66. 5 ng /mL) respectively. Conclusion: The method was accurate, reliable and high sensitivity for determination of residual organic solvent in sulfadoxine.
