1、 高效液相色谱高效液相色谱 摘要摘要 高效液相色谱法又称“高压液相色谱”“高速液相色谱”“高分离度液相色谱” “近代柱色谱”等。高效液相色谱是色谱法的一个重要分支，以液体为流动相，采 用高压输液系统。 高效液相色谱用高压输液泵将具有不同极性的单一溶剂或不同比例的混合 溶剂、缓冲液等流动相泵入装有固定相的色谱柱，经进样阀注入待测样品，由流 动相带入柱内，在柱内各成分被分离后，依次进入检测器进行检测，从而实现对 试样的分析。这种方法已成为化学、生化、医学、工业、农业、环保、商检和法 检等学科领域中重要的分离分析技术，是分析化学、生物化学和环境化学工作者 手中必不可少的工具。 关键词： 液相色谱 高
