This may not be a direct answer to your question because the compunds I
work with are different from yours. I have used chiral HPLC columns
from two US companies to purify upto gram quantities of enantiomers;
Chiral Technologies (800-624-4725) and Regis Technologies
(847-967-6000). They might be able to help if you contact them.
