离心薄层层析仪是近年来国外发展起来的一种新的分离提纯仪器,用于有机化学、天然产物、染料、医药等方面的分离提纯效果较好。突出的优点是仪器简单,操作方便,节省时间和溶剂,如分离的条件选择适当,一般在30分钟就能完成一次制备量的分离。与之相比,柱色谱(包括高效柱在内)一般需要时间长,溶剂用量大,在除去大量溶剂时,很难避免样品的损失。为了尽快推广使用,为我国有机化学等领域提供一个新的分离手段,中国医学科学院药物研究所
Centrifugal thin-layer chromatography (TLC) is a new separation and purification instrument developed abroad in recent years. It is used for the separation and purification of organic chemistry, natural products, dyes, and medicine. The outstanding advantages are that the instrument is simple, the operation is convenient, the time and solvent are saved, and if the conditions for separation are properly selected, the separation of one preparation amount can generally be completed in 30 minutes. In contrast, column chromatography (including high-efficiency columns) generally takes a long time and the amount of solvent is large. When large amounts of solvent are removed, it is difficult to avoid sample loss. In order to promote its use as soon as possible, it will provide a new separation method for China’s organic chemistry and other fields.
