摘要
建立液固顶空毛细管气相色谱法测定甲苯咪唑中有机溶剂残留。采用HSS-4A和DB-1大口径毛细管柱,以正丁醇为内标进行定量。甲醇、乙醇、氯仿、甲苯及DMSO的回收率分别为103.8、100.2、103.2、109.8和90.5%。最低检测限分别为0.02、0.01、0.15、0.02和10.1μg·g-1。本方法简单、准确、灵敏度及重现性好。
To develop solution-solid headspace capillary GC for the determination of residual solvent in mebendazolc. Using HSS- 4A and DB-FFAP wide bore capillary column wish 1-butanol as internal standard. The average recovery of methanol, ethanol, chloroform, toluene and DMSO was 100.7 respectively. The lowest test limits of methanol, ethanol, chloroform, toluene and DMSO was 0.02μg·g^-1, 0.03μg·g^-1,0.05μg·g^-1,respectively. The method is simple, accurate, sensitive and reproducibility.
