Application

乙腈可作为：
  • 萃取溶剂，通过超高效液相色谱-串联质谱（UPLC-MS / Ms）定量分析食品 和茶叶 中的农药分析物、果汁和葡萄酒 中的工业染料。
  • 有机改性剂，通过快速LC-MS/MS测定罐头食品和饮料中的双酚A-二缩水甘油醚、双酚F-二缩水甘油醚及其衍生物。

乙腈是有机溶剂，作为流动相/萃取溶剂，通过超高效液相色谱 − 串联质谱（UHPLC-MS）分析烟草样品中的杀虫剂情况。 可与反相色谱柱结合使用，确定双氯芬酸（DCF）浓度。

General description

乙腈为脂肪族腈，是具有高度挥发性的非质子极性有机溶剂，广泛应用于各类分析测定。由于紫外线可以透过 − ，其可应用于分光光度法和荧光法分析。乙腈具有低粘度、高洗脱强度且在水中可混溶的特点，能在许多色谱体系中应用。
其他应用还包括在各类色谱应用中作为流动相添加剂和作为萃取溶剂，用于液-液萃取（LLC），固相萃取（SPE）和微萃取等。
