Malvern Instruments has launched the Zetasizer µV with OmniFACE and OmniSEC, a new SEC-LS (size exclusion chromatography - light scattering) detector package dedicated to protein analysis.  

The proven Zetasizer µV 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 µV 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 µV 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 µV 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 µV 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 µV ensure excellent baseline stability and signal-to-noise for maximum sensitivity, while the 8 μL flow cell minimizes band broadening.
