摘要
应用Agilent 6890 plus气相色谱仪(配有FID),把一根50m×0.25mm×0.5μm PEG-20M毛细管色谱柱和一根100m×0.25mm×0.5μm HP-1毛细管色谱柱串接,使得甲基叔丁基醚(MTBE)能和石脑油中其它组分完全分离,解决了石脑油中微量MTBE的测定难题。方法的标准偏差是0.20%,回收率为100%。
Agilent applied, and one 6890 plus gas chromatography 50 m ×0.25 mm × O.5 μm PEG-20M capillary is linked with one 100 m × 0.25 mm × O.5μm HP-1 capillary in series. This can make MTBE and naphtha separated completely. So problem is solved to test the trace MTBE in naphtha. The standard deviation of this method is 0.20%, and recovery rate is 100%.
