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.
This application note presents an analysis of fluid cat cracker feed using an Agilent J&W FactorFour VF-5ht UltiMetal column. The column is developed using proprietary UltiMetal technology which provides a virtually unbreakable metal column material with excellent inertness properties similar to fused silica tubing. The UltiMetal tubing is coated with the VF-5 low bleed arylene stabilized liquid phase, resulting in a highly temperature stable and durable column perfectly suited for a variety of high temperature applications.
