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.

There is a strong global trend in automotive design that features a continuous increase in the use of conventional, performance, and novel polymeric materials. This is a result of weight savings, design flexibility, and ease of fabrication offered by...
Gel Permeation Chromatography (GPC) also known as Size Exclusion Chromatography (SEC), is a very popular analytical tool for polymer characterization. Low molecular weight polymers such as polyols, epoxies and polycaprolactones (amongst others) are u...
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.
Here, we will show how to separate the effects of a structural difference induced by a compositional change to a polymer (e.g. substitution) and the structural change induced by polymer chain branching, using OMNISEC.
A selection of different PLA and PLGA polymer samples were analyzed on Malvern's OMNISEC GPC/SEC system, which combines multiple detectors to provide information about structure and solution properties.
