This paper deals with the use of polystyrene gels in high performance liquid chromatography for preparative separations of small molecules with very similar structures. The preparative chromatograph, equipped with a recycle device and made in our laboratory, is described. The column set, consisted of three columns packed with low porosity polystyrene gel. The mobile phase was diisopropylether. Three particle sizes (10μ, 20μ, 50μ) were studied for improving the preparative performance. We checked the very high efficiency of our recycling system versus sample load. High sample loadings (up to 100 grams) can be injected when the separation does not require a large number of plates but typical sample loads are 10-20 grams for high performance separations. Some examples of separation of diastereoisomers, configurational isomers or related structure molecules are given. The advantages of our preparative system are discussed. |
