摘要
介绍了采用大口径(0.53mm)毛细管色谱柱,热离子特殊检测器(TSD)测定乙腈抽提的丁二烯中微量乙腈的方法。该法最低检出量达0.1mg/kg,分析时间仅需3min。与国家标准方法GB6015-85比较,该法灵敏度高,分析时间短,具有显著的技术先进性和实用性。
The method of determination of trace acetonitrile in the extract of butadiene is introduced. The method applies capillary column with large inside diameter and a thermionic specific detector. The detection limit reaches 0.1 mg/kg, and the test time is only 3 min. Compared with the national standard GB601585, the method has the advantage of higher sensitivity and shorter test time.
