This document describes the application of Agilent PLgel 10 µm MIXED-B columns in high molecular weight polymer analysis and demanding eluent conditions, such as polyvinyl pyrrolidone in dimethylformamide (DMF). Polyvinyl pyrrolidone is soluble in both polar organics and water. DMF is used with LiBr to minimize any polyelectrolyte effects. The document also highlights the features of PLgel MIXED-B columns, which are particularly useful for molecular weight distributions where slightly higher than average MWs are encountered.
