摘要

Countercurrent chromatography (CCC) is a technique that was first invented in the mid 1960's. After a brief period of interest by many scientists, the technique declined in popularity, being effectively out-competed by rival techniques that were faster and more reliable. To many, CCC was known as a slow technique with separations measured in hours or days, with poor capacity allowing injections of only tens of milligrams, poor reliability and difficult scale-up because of a poor understanding of the factors required to scale up or instruments on which to do so. However, recent engineering improvements and advances in the understanding of the process have transformed the technique to one which provides separations in minutes, injection loadings in the scale of grams to hundreds-of-grams, equipment that is considerably more robust and a scale up from analytical to pilot level that is quick and easy.
