WebMultiangle light scattering (MALS) describes a technique for measuring the light scattered by a sample into a plurality of angles. It is used for determining both the absolute molar mass and the average size of molecules in solution, by detecting how they scatter light.A collimated beam from a laser source is most often used, in which case the technique can … WebApr 9, 2024 · The solid angle depends on the shape of the object and the distance between the observer and object. In this research, the source is the observer and the detector is the object. A detector system records a signal over a set period of time (integration time) and reports the summed value (count).
