A guide to low angle light scattering
Unlike multi-angle light scattering techniques that can only determine molecular weight by extrapolation, the Lals technique measures molecular weight directly
Viscotek has published a new technical booklet that explores the principles of measurement and operation of the low angle light scattering (Lals) detector Unlike multi-angle light scattering techniques that can only determine molecular weight by extrapolation, the Lals technique measures molecular weight directly and, says Viscotek, is therefore inherently more accurate

Absolute molecular weights without extrapolation
Viscotek has announced new technical data that demonstrates how its unique low angle light scattering (Lals) detector achieves results not possible using traditional light scattering technologies.
Consequently the technique is of considerable importance to scientists looking to make routine direct determination of absolute molecular weights of polymers and proteins.
Written by Max Haney, an authority in the field of natural and synthetic polymer characterisation by GPC, the booklet was produced in response to a growing requirement from scientists for a short and unbiased introduction to the analytical techniques they use.
The technical booklet provides an introduction to the theory of light scattering detection and then leads the reader through a discussion of why low angle light scattering measurement is important.
The discussion is accurately illustrated with application examples and supported with mathematical theory. Request a free brochure from Viscotek Europe ...
