GPC/SEC Analysis of Polylactic Acid (PLA) and Poly(Lactic-Co-Glycolic Acid)(PLGA) Using OMNISEC

The biodegradable and biocompatible polymers, PLA and PLGA are used in many different applications including food packaging, farming materials, biomedical devices such as absorbable surgical thread and implants such as stents or drug release systems. In this application note, a selection of different PLA and PLGA polymer samples were analyzed on Malvern's OMNISEC GPC/SEC system.
