The Viscotek SEC-MALS 20 is the most advanced multi-angle light scattering detector, for GPC / SEC, on the market

The Viscotek SEC-MALS 20 is the most advanced multi-angle light scattering detector,     
for GPC / SEC, on the market. It measures the intensity of scattering at each angle simultaneously, which in conjunction with a concentration detector is used to calculate absolute molecular weight of proteins, synthetic & natural polymers, and also molecular size expressed as the radius of gyration, Rg.     
                     
The SEC-MALS 20 is a modular detector that can easily be used with any existing SEC system, adding the power of light scattering detection for molecular weight and size    
measurements. It can also be purchased as part of a complete system package. With a high number of measurement angles and also the best performance at lower angles, the SEC-MALS 20 is superior to traditional MALS instruments. This is achieved using a vertical flow cell with radial optics to minimize the detector noise and maximize the sensitivity.                     
                     
For proteins SEC-MALS measures the absolute molecular weight independent of column retention volume in order to study oligomeric state and aggregation. In combination with two concentration detectors, SEC-MALS can also measure the molecular weight of conjugates such as PEGylated and detergent soluble proteins.
