By applying an enhanced approach, a greater understanding of the methods used in a shorter amount of time can be obtained. Kimber Barnett from Pfizer discusses if using an enhanced (or Quality-by-Design) approach to chromatographic method development revealed the severity of effect of any specific method parameter that may have been missed if another approach was taken. read more

Gel permeation chromatography/size-exclusion chromatography (GPC/SEC) is a powerful tool for determining the complete molar mass distribution of macromolecules. Recent design advances are creating new opportunities to use GPC/SEC for challenging analyses such as copolymers. In this eBook, experts discuss how several GPC/SEC methods may improve copolymer sample characterization. Learn about dual-detection methods, polymer liquid adsorption chromatography, 2D chromatography, and more.  Download the eBook
