Hi Tee, 
 I discussed this with a GPC expert and we came out with an article that might help you: 1773 (researchgate.net) 
 In this article 3 columns with different pore sizes are coupled to get the necessary resolution over a broad MW range. 
 You can also use a set of PLgel 3 &micro;m MIXED-E columns and here is an example for a polystyrene standard: 5990--7937EN_5989_5672.qxd (agilent.com) . Keep in mind that you probably also need two or three columns in series to achieve a good resolution. You can find the part numbers of all these columns in the catalog above.

 Norbert
