高温液相色谱(High temperature liquid chromatography,HTLC)是一种操作温度在常温以上,通过改变温度来对分析仪器进行调节的液相色谱分析方法。实验采用接触预热法,检测器后设置阻尼阀的方式,通过在色谱柱后及检测器前直接设置冷却管的方式构建了分离效率高、峰容量大及可采用高黏度溶剂为流动相的HTLC系统。
High temperature liquid chromatography (HTLC) is a liquid chromatographic method that operates at temperatures above room temperature and adjusts the analytical instrument by changing the temperature. The experiment uses the method of contact preheating and the setting of the damping valve after the detector. By setting up the cooling tube directly behind the column and before the detector, the separation efficiency is high, the peak capacity is large and the solvent with high viscosity can be used as the mobile phase HTLC system.
