Preparative Fractionation by CRYSTAF

In some complex resins, a fractionation by TREF would not render the expected results, for this reason CRYSTAF mode is a more convenient method. This fractionation method is more time consuming than in TREF mode because of the redissolution and crystallization steps, which need to be performed for each fraction.
