近年来,薄层色谱(TLC)技术已发展成为一种重要的分析手段。由于它所需要的设备、条件简单,造价低廉,检出灵敏度高,分离效果好,用样少而且不破坏样品,操作方便、快速,因此容易建立和推广。 薄层色谱是利用混合物中各组分的物理化学性质的差异,使各组分在固定相和流动相中的分配系数(或吸附平衡常数)不同,引起各组分迁移速度的差异而得到分离。正
In recent years, thin layer chromatography (TLC) technology has developed into an important analytical tool. Because of the equipment it needs, the conditions are simple, the cost is low, the detection sensitivity is high, the separation effect is good, the sample is used less and the sample is not damaged, and the operation is convenient and fast. Therefore, it is easy to establish and popularize. Thin-layer chromatography is the use of the mixture of the physical and chemical properties of the various components of the differences in the stationary phase and the mobile phase of the partition coefficient (or adsorption equilibrium constant) is different, causing differences in the rate of migration of components to be separated . positive
