  • Enhanced Purification of Capsaicins with the CombiFlash® EZ Prep

    Abstract In this application note, capsaicins are used as a model for compounds difficult to resolve with flash chromatography. Capsaicin compounds possess very similar structures making them difficult to resolve from each other. Although these compounds can be resolved on flash chromatography columns, such as the RediSep® Rf Gold C18, preparative high pressure liquid chromatography ...
