I am looking for suggestions on a void volume marker for use with a HILIC silica stationary phase in conjunction with acetonitrile / ammonium formate buffer system.

Off the top of my head, I'd say somerhing like anthracene, but check with the column suppliers (the usual suspects) and see what they use when they test the columns.
