摘要: 目的 用气相色谱法测定三氯苯达唑中有机溶剂残留量。方法 采用高效毛细管色谱柱INNOWAX(30m×0.32mm×0.25μm),检测器为FID,应用程序升温,直接进样法检测。结果 两个测定系统中乙醇、DMF、乙酸与所用内标、溶剂互不干扰,分离度及检出灵敏度均达到要求,三成分的最小检出浓度分别为2.03μg/mL、2.21μg/mL与3.75μg/mL。结论 本方法能准确控制样品中残留溶剂,控制产品的质量。Abstract: OBJECTIVE To establish a GC method for the determination of organic solvents remaining. METHODS The methods was approved by high efficiency chlomatogram column of INNOWAX(30m×0.32mm×0.25μm),with a detector of FID using direct injection. RESULTS:There is no interfere of every component between ethanol,DMF,acetic acid inside standard and solven. The resolution and sensitivity were acceptable. The detection limit of the three components were 2.03μg/mL, 2.21μg/mL, 3.75μg/mL respectively. CONCLUSIONS This method is accurate to control the organic solvents remaining.
