신제품 GPC 검출기 – VISCOTEK SEC-MALS 20

 THE VISCOTEK SEC-MALS 20
MORE ANGLES, MORE DATA, MORE CHOICE

 

 

 

 

 

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 minimise the detector noise and maximise 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 

 


For natural and synthetic polymers MALS provides molecular weight and Rg. It also offers insights into molecular structure through conformation plots of Rg with molecular weight. 

 


The Viscotek SEC-MALS 20 is an advanced light scattering solution for the characterization of all sample types by advanced GPC/SEC.
