Conditions Sample: Water soluble copolymer Columns: 2 x PL aquagel-OH 50 8 μm, 300 x 7.5 mm (p/n PL1149-6850) Eluent: 0.2 M NaNO 3 + 0.01 M NaH 2 PO 4 at pH 7 Flow Rate: 1.0 mL/min Detection: RI CH 2 HC N CO Conclusion n CH 2 CH NH 2 Figure 1. Raw data chromatogram of poly 2-vinyl pyridine Size exclusion chromatography using PL aquagel-OH columns successfully analyzed a sample of water soluble copolymer. Aqueous SEC with PL aquagel-OH columns provides information not only on the molecular weight of the polymer but also on the polydispersity and the shape of the molecular weight distribution. The excellent chemical and mechanical stability of these columns offer high performance with good repeatability and column lifetime. m 10 min 20 Figure 2.

Authors Greg Saunders, Ben MacCreath Agilent Technologies, Inc. SEC Analysis of a Acrylamide Copolymer Application Note Introduction This sample is a copolymer of acrylamide and dimethylaminoethyl acrylate quaternized with methyl chloride. It was necessary to maintain a low sample concentration (0.1 %) to minimize problems of shear with this high molecular weight polymer. The sample was assessed by aqueous SEC with Agilent PL aquagel-OH 40 and 60 15 μm columns. These columns were employed in order to avoid on-column shear degradation, and cover a molecular weight range from 10 4 to 10 7 .
