Size Exclusion Chromatography
Although size exclusion chromatography (SEC) is perhaps the most popular and widely used technique for determining the molecular weight distribution of polymeric materials, there have been very few texts written on this topic. During the past decade, SEC

Preface
The molecular weight (MW) and molecular weight distribution (MWD) of polymers are perhaps their most important characteristics, governing both physical properties and end-use applications. As a result, MW and MWD are needed to establish structure-property-processing relationships for the development of new products and the improvement of existing materials. Furthermore, these measurements are needed to access the quality of a material, and for process control and monitoring polymerization kinetics. Size exclusion chromatography (SEC), also referred to as gel permeation chromatography or gel filtration, is the most widely used method for determining MW and MWD. Almost every manufacturer or laboratory involved with polymeric materials is or should be involved with this analytical technique. Unfortunately, the theory and practice of SEC is not a customary part of one's analytical training, and must be learned on the job. Furthermore, during the past several years, there have been significant advances in SEC colum
