I am looking for a source for the Following HPLC column:
150 mm X 4.6 mm anion exchange resin R1. It is described as "A resin containing quaternary ammonium groups lattice consisting of methacrylate".
Any help is appreciated.

Since nobody is answering, maybe a "non-answer" will help:
We have been using Poros R1 from PerSeptive (Applied Biosystems). Thatīs a polymer material for reversed phase LC.

Bio-Rad lists Bio-Scale Q columns in their catalog. Bio-Scale Q is quaternary ammonium derivative of methacrylate macroporous polymer and is made for protein and DNA purification. Also search TosoHaas for similar products.

Protein-Pak HR Q columns from Waters are made from a methacrylate polymer with a pore size of 1000 Angstroem. They are designed for protein separations. Sorry for the commercial!
