Hexafluoroisopropanol (HFIP) is used as a solvent in GPC for the analysis of important industrial polymers
such as polyesters, polyamides and polylactide/glycolide copolymers. For greatly improved performance in
extremely polar solvents such as HFIP and trifluoroethanol, we have developed novel "multipore"
technology to produce PL HFIPgel, a PS/DVB packing featuring a monodisperse particle size, high pore
volume, and high resolution.
Using PL HFIPgel avoids issues associated with conventional packings and HFIP, such as excessive
curvature of calibration curves, dislocations/shoulders on peaks for polydisperse samples, and poor
resolution in the low MW region.
