气相色谱法测定阿克他利中的有机溶剂残留量

目的：建立毛细管气相色谱法测定阿克他利中的有机溶剂残留量。方法：采用HP-FFAP毛细管气相色谱柱,FID检测器,以正丙醇为内标进行测定。结果：乙醇、醋酸、DMF的线性范围分别为50～800μg/ml（r=0.999 9）、50～800μg/ml（r=0.999 7）和8.8～140.8μg/ml（r=0.999 9）;乙醇、醋酸、DMF的平均回收率分别为100.7%、100.2%和99.7%;RSD分别为0.87%、1.32%和1.47%（n=9）。结论：该方法简单、灵敏、准确、重现性好,适用于阿克他利中的有机溶剂残留量的测定。

Determination of residual organic solvents in actarit by capillary gas chromatography

Objective:To develop a gas chromatography method for the determination of residual organic solvents in actarit.Methods: The samples were injected into HP-FFAP capillary column and analyzed with FID detector using n-propanol as the internal standard.Results:The linear ranges of ethanol,acetic acid,DMF were 50～800 mg/L(r=0.999 9),50～800 mg/L(r=0.999 7) and 8.8～140.8 mg/L(r=0.999 9),respectively.The recoveries were 100.7%,100.2 % and 99.7 %,respectively;RSDs were 0.87 %,1.32 % and 1.47 %(n=9),respectively.Conclusion:The method is simple,accurate and sensitive with good reproducibility,and can be used for the determination of the residual organic solvents in actarit.
