AN INTEGRATED ON-LINE TWO-DIMENSIONAL METHOD AND DEVICE FOR SYNCHRONIZED ANALYTICAL TEMPERATURE RISING ELUTION FRACTIONATION AND GEL PERMEATION CHROMATOGRAPHY

摘要

An analytical method comprising performing a first fractionation of a polymer sample based on differences in crystallizability to provide a first set of sample fractions, performing a first analysis on the first set of sample fractions, performing a second fractionation of the first set of sample fractions to produce a second set of sample fractions, performing a second analysis on the second set of sample fractions, and synchronizing the first fractionation and second fractionation to provide about concurrent analysis of the polymer sample.
