The authors describe a system for automated analytical temperature-rising elution fractionation that uses the built-in differential refractometer of a commercial-gel-permeation chromatography instrument and a stop-flow method for sample crystallization. They discuss the performance of the system and its ability to fractionate different types of polyethylenes.
