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.
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.
