I used a  Pharmacia mono-Q HR-5/5 column, but it required 4 to 8 hour
runs for each sample, and the product was eluted in a rather large volume
(500 microliters) of 0.75 M NaCl.  I decided that running 20 or 30
samples per hour in agarose was a better way to go.

Waters sells a Gen_pak FAX column that looks like it is supposed to do the
job in a 30 minute run.  They may be able to FAX you some info.  Their
phone number is (508) 478-2000  and their FAX number is (508) 478-7795.

Good luck.  Let us know how it works for you.  I suspect that you
will find you can process few samples per day, but that you will 
get very pure product and good quantitation of it.
