目的:建立气相色谱(GC)法测定棕榈哌泊噻嗪中二甲基亚砜(DMSO)有机溶剂残留量。方法:采用PC-624毛细管柱(60 m×0.32 mm,1.80μm),FID检测器,检测器温度为230℃,进样口温度为210℃,乙醇为溶剂。结果:二甲基亚砜与溶剂峰完全分离,DMSO在1.22～978.4μg·ml~(-1)浓度范围内线性关系良好(r=0.999 8),平均回收率为99.5%。结论:该方法可用于棕榈哌泊噻嗪中二甲基亚砜残留量测定。
OBJECTIVE: To establish a gas chromatography (GC) method for the determination of dimethylsulfoxide (DMSO) residues in palm Pipirothiazide. Methods: A PC-624 capillary column (60 m × 0.32 mm, 1.80 μm) with FID detector was used. The temperature of the detector was 230 ℃. The inlet temperature was 210 ℃ and ethanol was the solvent. Results: DMSO was completely separated from the solvent peak. The linear range of DMSO was 1.22 ~ 978.4μg · ml ~ (-1) (r = 0.999 8). The average recovery was 99.5%. Conclusion: This method can be used for the determination of dimethyl sulfoxide residues in.
