Malvern𠏋 new SEC-LS dual integrated detector is dedicated to proteins

UK | Posted on February 11th, 2011

The proven Zetasizer 猩 offers dual DLS (dynamic light scattering) and SLS (static light scattering) capabilities. It can be used as a stand-alone detector, analyzing samples in a cuvette, and now as a fully-featured modular chromatography detector. For protein applications, this makes the Zetasizer 猩 an ideal tool. Applications in stand-alone batch mode include the study of molecular size and formulation stability, and in SEC detector mode the measurement of molecular weight, determination of oligomeric state and detection and quantification of oligomers and aggregates. The absolute nature of the measurement means that no column calibration is required

The Zetasizer 猩 is available as a complete chromatography system or can be added to existing SEC modules. Malvern's OmniFACE provides the necessary connection that enables the Zetasizer 猩 to be linked into any third party SEC system and detectors, so that output signals can be used by the OmniSEC software for results calculation. Connecting the Zetasizer 猩 is simplicity itself. Using standard chromatography tubing it can be added in series with other detectors such as UV and RI.

The laser stability and optical setup of the Zetasizer 猩 ensure excellent baseline stability and signal-to-noise for maximum sensitivity, while the 8 閿 flow cell minimizes band broadening.

Malvern offers a range of solutions for characterizing natural and synthetic macromolecules. These include the Zetasizer family, employing dynamic and static light scattering to measure size and molecular weight; Viscotek advanced gel permeation chromatography/size exclusion chromatography (GPC/SEC) systems and detectors for rapid, reliable characterization of molecular weight and molecular structure; and the Sysmex FPIA-3000 for dynamic imaging including applications for characterizing sub-visible/visible particles and the size and shape of protein aggregates. www.malvern.com/Zetasizeruv
