Abstract

Gradient polymer elution chromatography (GPEC) is a reliable polymer separation method applied in many polymer labs. For many polymer researchers and HPLC users, GPEC is an unknown separation method. However, many of the basic rules regarding polarity of solvents, polymers and stationary phases of traditional HPLC are applicable also in GPEC. The main differences are based on the nature of high molar mass polymers, limited solubility and a molar mass distribution.
