Polylactic acid (PLA) and poly(lactic-co-glycolic) acid have become increasingly popular due to their renewable and biodegradable nature. As a result, these materials have found application in a variety of fields, including additive manufacturing, medical devices, and recyclable materials, among others. Because of the relatively low dn/dc values exhibited by PLA and PLGA, reliable data has historically been rare. However, the OMNISEC GPC/SEC system, with its increased sensitivity and multi-detector capabilities, has proven to be a valuable tool for researchers and manufacturers thoroughly characterizing these sample types.
At Malvern Panalytical, my colleagues and I have had the opportunity to analyze a range of PLA and PLGA samples in recent years. As a result, the collection of Application Notes and other documents below highlight how the OMNISEC system can offer insight regarding the molecular properties of your samples.
