Can anyone suggest a column to separate Triethylamine (TEA) and Isopropyl alcohol (IPA) in chloroform sovent? It seems that columns that give a good peak shape for one component give tailing peaks for the other. Thanks.

Supelco Catalog # 1-1887 packing
4% Carbowax 20M/0.8% KOH on Carbopack B 60/80 mesh
in a 2m x 2mm IC glass column
at about 80C 20-30cc/min Helium

Or ( not sure about retention times)
any deactivated Bonded Carbowax capillary
deactivated for amines.

Rod-
Supelco produces a Carbowax amine deactivated column that I found to work nicely for my application. Thanks for the advice.
