Multiangle light scattering instruments

If a multiangle light-scattering instrument is used, the mean-square radius of gyration (Rg )i at each elution volume can also be obtained from the particle scattering function...

In recent years, multiangle laser light scattering (MALLS) detectors have become highly popular in SEC and also in FFF (see,e.g. [135-140]), since they also determine molar masses and molecular dimensions on an absolute basis. Here, the scattered light is simultaneously detected at various angles so that an extrapolation to zero angle is possible. Such instruments are commercially available from several companies. As an important development, the FFF-MALLS combination is discussed in a separate chapter (see Sect. 4.1.2).
