I would appreciate it if anyone can send me info about the commercial availability of GC columns with a liquid crystal stationary phase.
The reason is that I am looking for a column that separates according to molecular size. Mol sieve and PLOT columns can be use for such separations, but are limited in terms of the carbon numbers that can be separated and also they can not handle oxygenates (like alcohols and ketones) present in samples.
A recent article in Chromatographia (2002,55,No 9/10 p523-531), G.Felix states that GC columns based on side-chain liquid-crystal polymers are now commercially available. The question is: Where?

I would go on and send an e-mail directly to the author. It might be difficult to find these type of columns if ever their construction has been undertaken by a small company.

Thanks for the contribution Anonymous (Aug.15), but that was the first thing I have done. My email returned with an unknown address message.
