High-Performance SEC Column Technology

Although size exclusion chromatography (SEC) is a fairly mature separation technique, improvements are continually made in packing technology. Howard Barth and Greg Saunders review some of the basics of SEC and look at the current status of column technology, including developments for faster and higher resolution size separations.

Polymer Analysis by Gel Permeation Chromatography — A Historical Perspective

This article discusses the development of gel permeation chromatography or size exclusion chromatography as a technique for analysing the molecular weight distributions of polymers. It further highlights the development of columns and hardware for high-resolution characterization of polymers.
