在有机合成及天然有机产物的结构鉴定中,分离纯化是一个经常遇到而必须解决的问题。各种色谱是进行分离纯化行之有效的方法。制备性液相离心色谱是近年来发展起来的一种新方法。由于仪器简单,使用方便,分离效果好,所以颇受欢迎。本文以Chromatotron7924型仪器(美国Harrison Research制造)为例,对制备性液相离心色谱作一简单介绍。一、原理和仪器装置。离心色谱除了吸附剂因素之外,主要是利用离心力来达到分离的目的。仪器主要由分离圆转盘,洗脱液装置和检测等部份组成。 1.分离圆转盘装置。固定薄层吸附相
In the organic synthesis and the natural organic product structure identification, separation and purification is a frequently encountered and must be addressed. A variety of chromatographic separation and purification is an effective method. Preparative liquid chromatography is a new method developed in recent years. As the instrument is simple, easy to use, the separation effect is good, so popular. In this paper, Chromatotron7924 instrument (Harrison Research made in the United States), for example, preparative liquid-phase centrifugal chromatography for a brief introduction. First, the principle and instrumentation. Centrifugal chromatography in addition to adsorbent factors, the main use of centrifugal force to achieve the purpose of separation. The instrument is mainly composed of separation dial, eluent device and detection. 1. Separate the turntable device. Fixed thin layer adsorption phase
