一般說明

二氯甲烷是一种极性和高挥发性有机化合物(VOC),以其在工业界有多种用途而为人熟知。它可以作为萃取溶剂、金属清洁剂和日常消费品,如粘合剂、鞋抛光喷雾、油漆和粘合剂清除剂。

應用

二氯甲烷可用于以下情况:

  • 使用分散液-液微萃取法(DLLME)从蜂蜜样品中提取新烟碱类化合物
  • 通过液相色谱-串联质谱(LC-MS/MS)分析超声溶剂萃取并净化的烘焙咖啡样品中7种杀虫剂残留
  • 基于DLLME的样品提取物的额外预浓缩,用于通过带有UV检测器的HPLC分析动物源食品中的三种酰氨醇类抗生素
  • 使用HPLC测定两种磺酰脲类除草剂时,去除获取的土壤样品提取物中有机相
  • 开发基于HPLC-安倍检测法分析液态和固态食品样品中三种氨基甲酸酯农药残留时,测试四种萃取溶剂
  • 通过基质固相分散法(MSPD)从蔬菜样品中提取苯菌酮再用HPLC分析

适用于HPLC、分光光度法、环境检测
