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.
End of tedious column
calibration; MW is independent
of elution volume
20 detectors for improved
angular coverage
Multiple low angle and low
noise detectors to improve
accuracy
Single flow cell compatible
with all solvent refractive
indices
Vertical flow cell with
advanced radial optics for
improved performance
Compatible with any
GPC/SEC system
Small footprint
Easy conversion from left
or right connection
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
