    摘要： The invention provides a method for one-dimensional chromatography of a polyolefin polymer, comprising introducing a solution of the polyolefin polymer into a liquid flowing through a liquid chromatography stationary phase, the liquid chromatography stationary phase comprising graphitic carbon, and wherein the polyolefin polymer emerging from the liquid chromatography stationary phase has a retention factor greater than zero, and wherein the solution introduced into the liquid chromatography stationary phase is subjected to a temperature gradient, and/or the solution is subjected to a solvent gradient. The invention also provides 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, and wherein the polyolefin polymer emerging from the liquid chromatography stationary phase has a retention factor greater than zero. The invention also provides an apparatus for polyolefin polymer chromatography, comprising a liquid chromatography stationary phase, the liquid chromatography stationary phase comprising graphitic carbon and at least one inert filler.
