Organic polymer-based high-efficiency columns

A New Family of Organic Polymer-Based High-Efficiency Gel Permeation Chromatography Columns... [Pg.145]

For the analysis of organic-soluble and water-soluble synthetic polymers, silica-based packing materials have not become as widely used as was originally envisioned (8). Major improvements in the properties of polymer-based supports have contributed to their increased use in GPC. Columns packed with polystyrene divinylbenzene particles are now as efficient as those filled with silica particles of the same size. Because polymer-based packings can be synthesized with very small (<60 A) and very large (>4000 A) pores, they provide better selectivity than silica columns for the separation of monomers, as well as for very high molecular weight (5-20 million dalton) polymers. [Pg.48]

The organic matrices are based on natural or synthetic polymers. This group of stationary phases has high capacity, high chemical stability, but low column efficiency it is promising for preparative apphcations. [Pg.1339]
