超临界流体色谱兼有气相色谱和液相色谱的特点。它既可分析气相色谱不适应的高沸点、低挥发性样品,又比高效液相色谱有更快的分析速度和条件。操作温度主要决定于所选用的流体,常用的有二氧化碳及氧化亚氮。超临界流体容易控制和调节,在进入检测器前可以转化为气体、液体或保持其超临界流体状态,因此可与现有任何液相或气相的检测器相连接,能与多种类型检测器相匹配,扩大了它的应用范围和分类能力,在定性、定量方面有较大的选择范围。还可以用多种梯度技术来优化色谱条件。并且比高效液相色谱法易达到更高的柱效率。 仪器主要由三部分构成,即高压泵、分析单元和控制系统。高压泵系统一般采用注射泵,以获得无脉冲、小流量的超临界流体的输...
