Low angle laser light scattering device

Molecular weights of samples were determined by a low-angle laser light-scattering device in pure DMSO. 

The advanced models of GPC are equipped to measure the MW of the eluting polymer with a low angle laser light scattering device (FALLS). This enables the calibration problem to be eliminated. A special attachment to measure the viscosity of the eluting solution is also available. From the above two measurements a degree of branching may be estimated. The information on the branch pattern is not obtainable, however.
