A method of analyzing a polymer resin comprising: providing a polymer resin sample having two or more polymer components; subjecting the sample to aTREF analysis to yield aTREF elution trace by contacting the sample with aTREF solvent to form sample solution; introducing sample solution into aTREF column and allowing elution of polymer components at different elution rates along the column; eluting from the aTREF column an aTREF eluent comprising the polymer components eluting at different rates; and subjecting the aTREF eluent to IR detection to yield the aTREF elution trace; identifying the components of the sample to yield identified components by comparing the elution trace with an identification library that comprises a plurality of known polymer aTREF elution traces correlated with known polymer components characterized by identifying parameters (density, SCB, crystallization temperature, MI, HLMI, MWD); and quantifying each of the identified components to yield quantified polymer components via chemometric analysis.
