unretained analyte for a 1000A SEC column

Hi,

Can anybody help me with finding an analyte to determine the exclusion volume for a 1000A pore size SEC column. The column can separate analytes up to 8MDa. Even the manufacturer cannot provide me with either information about exclusion volume nor analytes to use.
what could I use?

Cheers,
Chris
