Method of choice: The combination of size exclusion chromatography (SEC) and light scattering detection (LS) determines molecular weight, especially for higher molecular species such as aggregates or oligomers. As an additional plus sample size and topology can also be revealed. Special attention needs to be turned to the quality of SEC columns in order to provide signals unaffected by spikes. YMC’s SEC columns support LS-detection perfectly due to a high level of inertness...
