An integrated online analytical device elution fractionation synchronized increased temperature and gel permeation chromatography method bidimensional

摘要

An analytical method comprising: (a) performing a first fractionation of a polymer sample based on differences in Capacity to crystallization to provide a first set of sample fractions; (b) performing a first analysis on the first set of fractions samples; (c) performing a second fractionation of the first set of sample fractions to producirun second set of sample fractions; (d) performing a second analysis on the second set of sample fractions; (e) synchronizing the first fractionation and second fractionation to provide análisisconcurrente of the polymer sample, wherein the first fractionation is an analytical fractionation porelución temperature rising and wherein the second fractionation is chromatography degel rapid penetration.
