Web12 Aug 2013 · MALS provides key information into the angular dependence of the scattered light for large molecules of R g >10-15 nm radius, thus allowing for the more accurate R g measurement than a RALS/LALS hybrid. R g can be utilized for characterizing the structure for these large molecules. WebThe basic principle of Static Light Scattering at multiple angles (Multi-Angle Light Scattering) is the same as the principle of Static Light Scattering at one single angle. A beam of polarized light is focused onto the sample molecule and the scattered light is detected with a photo detector.
