Would anyone like to recomend a GPC column? I am analyzing polyesters with a Jordi Xtreme column
currently but want to try something else. Polymers are up to 3 million MW and solvent is HFIP.
If you google for GPC columns you will get information on all manufacturers and suppliers of GPC columns. It is impossible to recommend a GPC column. We would need to know from you what do you want to improve, why are you not satisfied with your actual GPC column?

My experience is more with prep GPC, but I can tell you that you need to look at the molecular weight exclusion limit when choosing a column. If your largest analyte is 3 million amu, look for a MWEL of 3 million or slightly higher. Anything above 3 million will be excluded and come out first.
