The Viscotek SEC-MALS 20 is a multi angle light scattering detector that can be used to measure the absolute molecular weight of proteins, synthetic and natural polymers, as well as molecular size expressed as the radius of gyration, Rg.

Overview

The Viscotek SEC-MALS 20 is a modular multi angle light scattering detector that can easily be used with any existing SEC system, adding the power of light scattering detection for molecular weight and molecular size measurements. It can also be purchased as part of a complete system package. The signals from the SEC-MALS and other detectors connected to the system are analyzed by the most advanced GPC software available, OMNISEC.

The SEC-MALS 20 can be used to measure the absolute molecular weight and oligomeric state of proteins, independent of retention time. It can also be used to analyze natural and synthetic polymers, including the measurement of molecular size over the widest possible range.

How it works

The SEC-MALS 20 multi angle light scattering detector is connected to the output of any SEC or GPC system, such as the OMNISEC. Signals generated from the sample passing through all detectors are analyzed by OMNISEC software.

The SEC-MALS system consists of 20 detectors arranged around a vertical flow cell to detect scattered light at a wide range of angles.
