摘要:
对3类适用于酚类物质的衍生方法进行比较。结果显示,3种衍生方法均具有改善峰形、提高检测灵敏度、降低检出限等优势。其中七氟丁酸酐衍生法具有较大的腐蚀性;TMS衍生体系对水分非常敏感,需确保衍生体系脱水充分;五氟苄基溴衍生相对更成熟和完善。

Abstract:
Three appropriate category derivatization methods were selected and compared for phenolic compounds. The results showed that the three derivatization methods all had many advantages, such as improving the peak shape, improving the detection sensitivity, and lower the detection limits, etc. Wherein heptafluoro butyric anhydride derivatization method was relatively more corrosive; TMS derivatization system was very sensitive to water, and adequate dewatering was necessary; pentafluoro benzyl bromide derivatization method was relatively more mature and perfect.
