高效液相色谱(HPLC)是现代化合物分离鉴定的重要手段,然而,由于缺少通用检测器、样品被测组分含量低及其本身性质的限制,并非所有化合物都可直接用于高效液相色谱分析。衍生化反应可改变被测化合物性质,使之能够快速、灵敏、准确地被测定。
百灵威提供紫外、荧光等多种HPLC衍生化试剂。
常用紫外衍生化试剂
高效液相色谱大都配备紫外检测器,为使一些没有或有很弱紫外吸收的化合物能被检测,往往需要通过衍生化反应,在这些化合物分子中引入具有强紫外吸收的基团,使衍生物可被紫外检测器检测。

常用荧光衍生化试剂
荧光检测器具有高灵敏度和高选择性,比紫外检测器的灵敏度高10‐1000倍。荧光衍生化试剂能与一些官能团产生强烈荧光,在较温和条件下与被测物质快速定量反应,尤其适合痕量组分分析。
