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.

Using OMNISEC, 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.
In this application note, 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.
In this application note, the molecular weight, molecular weight distribution and size of common polymers are measured using the OMNISEC system.
In this application note, the structural distribution of some common polymers are compared using the Mark-Houwink plot. The data are all generated using the advanced OMNISEC multi-detector GPC/SEC system
This technical note describes the features and benefits of OMNISEC RESOLVE. It also includes a discussion of the value of OMNISEC as a complete system as opposed to upgrading an existing conventional system to advanced detection.
