SEC Handbook
Author(s)Tosoh Bioscience
Polymers, generally referred to as plastics or resins, are used for a variety of purposes and have become deeply entrenched in modern life. As the petrochemical industry that produces polymers continues to grow, polymers with new structures and specialized functions continue to be developed and manufactured. Size exclusion chromatography (SEC) is a widely used technique for assessing the molecular mass of these polymers. This handbook introduces the basic principles of SEC, along with methods of analysis and examples of analysis of real samples.
