All-
Can anyone suggest to me where I can purchase certified pullulan standards for aqueous GPC analysis with Mp in the 750kD - 1500kD range? A google serch reveals only a few of these available and only as part of a much more expensive kit. Thanks in advance.

You may also want to contact American Polymer Standard Corporation. They are located in Mentor Ohio. They will also provide you with validated Mp, Mn, and Mw values if you require it. However this will cost you extra. Hope this helps
