Malvern Instruments’ launch of the Viscotek SEC-MALS 20 multiple angle light scattering (MALS) detector can now be viewed online.
With this extension to its range of GPC/SEC detectors, Malvern claims to be the only vendor to offer all types of static light scattering detector routinely used for absolute molecular weight measurement.
The full launch webinar is available while a 3-minute video which gives a basic introduction to the new system is available on YouTube.
Static light scattering is widely used within gel permeation/size exclusion chromatography (GPC/SEC) for the determination of the absolute molecular weight of protein, polymer and macromolecular species without the need for external, potentially inaccurate calibrations.
The Viscotek SEC-MALS 20 offers numerous operational features designed to increase accuracy and operational ease of use.
Malvern says it incorporates more detectors than any other commercial alternative and that the increased detection at lower angles provides a significant improvement in accuracy, even at high molecular weights.
The vertical sample flow cell with radial optics allows the use of a variety of mobile phase solvents, without the need for optical readjustment.
Malvern’s static light scattering detectors, which include low angle, right angle and multi angle detectors, are available individually and are compatible with any commercial GPC/SEC system, or may be supplied integrated within a multi detection Viscotek system for comprehensive polymer, protein and macromolecule characterisation.
