The molecular weight of proteins, synthetic and natural polymers is a direct indicator of product performance and activity.
Understanding this and other molecular parameters is key to controlling product performance in a wide variety of applications areas including:
Malvern’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. Complete systems such as the TDAmax form and out-of the-box solution, while add-on detectors such as the SEC-MALS 20 and the Zetasizer µV allow you to upgrade an existing GPC/SEC system to measure absolute molecular weight.

In this work three commercially available Low Molecular Weight Heparin samples (Enoxaparin, Tinzaparin and Dalteparin) are measured by triple-detection GPC and any differences identified. In addition, structural comparisons will be made with a commer...
In its report ‘Critical Path Opportunities for Generic Drugs’, the FDA emphasizes the need for advances in the field of analytical sciences in order to accelerate the development of generic products. Here, Paul Kippax highlights techniques that are e...
A variety of aqueous (water-soluble) cellulose derivatives were characterized using the OMNISEC triple detection GPC/SEC system which revealed subtle, yet distinct differences between them. The differences described in this application note could be ...
Two antibody samples were characterized using column calibration and multi-detection SEC, and the results compared to show how multi-detection SEC provides more accurate data and a more complete characterization of the protein mixtures under study.
