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.

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