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.

GPC/SEC can be used to characterize commodity or bulk manufactured polymers. Here we describe how the use of formic acid instead of HFIP as the dissolution solvent and/or mobile phase can lead to improvements in both cost per analysis and health and ...
Size exclusion chromatography (SEC) is a chromatographic technique for the characterization of proteins and biopharmaceuticals, as well as natural and synthetic polymers. Traditional systems comprised a single concentration detector (Conventional Cal...
This webinar discusses how Malvern’s protein SEC measurement capabilities within the Viscotek range have developed and improved in the last year. We also introduce the new features that are included in the latest release of OmniSEC, including:
This technical note describes how to connect Viscotek detectors to Waters systems, in particular the Waters Alliance® system, and how to use OmniSEC in combination with Empower® to run trouble-free separation sequences.
In this application note, we show that Malvern’s OmniSEC software can now communicate with Waters Empower® for the seamless exchange of sample sequences. A selection of proteins was used to demonstrate the measurement of protein molecular weight, oli...
