Polymeric packed column for the analysis of water soluble high molecular weight polymers. Base material is polyhydroxymethacrylate, fulfills USP L38 and L39 requirements. Target molecular weight range: 500,000 - 500,000,000 Da. Large particle size and large pore size (30,000A) prevents shear degradation of polymers. Shipping solvent is water, usable pH range 3-10. Guard column SB-807G is recommended, part number 220-91668-01 with coupler 220-941524-97.
