Anion exchange column needed

[sball]

Dear all,

I am looking for a column that fits the European Pharmacopeia specifications of one packed with an "anion exchange resin R1". It needs to be 7um and in 150 x 4.6mm dimensions.

I have found a PRP-X100 and a MCI Gel SCA04 but these are only available in 5um particles sizes.

Does anyone know of a different column that fits the above requirements?

Thanks!

Sball,

You are correct, the PRP-X100 is only available in 3, 5 and 10µm particle sizes. The PRP-X110 however is available in 7µm particle size (4.6x150mm). The capacity of the X110 is lower compared to the X100 but otherwise the columns are identical. And I apologize for the rather product specific posting.

Best regards,

Robert, there is no reason to apologize. You had the expertise that could answer the question. Very few other people would have known that fact.

Thanks a lot for your help Robert. I hadn't heard of that column before.
