Multi angle detector for the use within laboratories where molecular weight, the radius of gyration and the second virial coefficient are determined according to the Zimm Plot method. Another field of application is the use as a multi angle light scattering detector for GPC/SEC. In connection with Windows-Software the detector is usable as USB-interface for other modules such as concentration detectors and the injector.

3.1) BI-MwA

The BI-MwA Molecular Weight Analyzer is simple to use, but incorporates sophisticated features. Inject your sample into the low-volume, 7-angle flow cell. The sample is illuminated by a temperature stabilized, precision power-controlled diode laser. The ultra-stable, high-sensitivity, low-noise CCD detector automatically collects the scattered light. Then, the software extrapolates the data to zero angle for the absolute molecular weight determination.
