Molecular weight

Understanding molecular weight determination, absolute molecular weight measurement and other molecular parameters is key to controlling product performance in a wide variety of application areas including:

• Strength, durability and toughness of plastics and other synthetic polymers
• Degradation and release rate of drug delivery polymers
• Performance and mouth-feel of polysaccharides in foods e.g. maltodextrin and other starch derivatives
• Strength and quality of fillers and lubricants in pharmaceuticals and cosmaceuticals e.g. hyaluronic acid and cellulose derivatives
• Efficacy and aggregation state of proteins and biopharmaceuticals e.g. monoclonal antibodies (mAbs)

Malvern Panalytical’s advanced GPC/SEC detectors, which include low angle and right angle light scattering (LALS and RALS) and multi-angle light scattering (SEC-MALS), are designed to measure absolute molecular weight with unparalleled accuracy. 

The OMNISEC system offers a complete stand-alone solution to measure molecular weight, and the OMNISEC REVEAL detector module can be used to upgrade an existing GPC/SEC system. The SEC-MALS 20 can be added to either of these solutions to add further capabilities to the solution.
