摘要：
A method for multi-dimensional chromatography of a polyolefin polymer, comprising introducing a solution of the polyolefin polymer into a liquid flowing through a first liquid chromatography stationary phase or a field flow fractionation device and subsequently flowing the solution through a second liquid chromatography stationary phase, the second liquid chromatography stationary phase comprising graphitic carbon, the polyolefin polymer emerging from the liquid chromatography stationary phase with a retention factor greater than zero.
