You might try using a non-ionic detergent such as Tween 20 to elute
your material. I have had success with this on Pharmacia
Phenyl-superose columns. The inclusion of 0.02% Tween 20 in the
elution buffer has both given me better yields of some proteins and
removed others that otherwise needed acetonitrile to get them off the
column. The elution position will be somewhat advanced but this need
not be a problem.
