Diffusion ordered NMR spectroscopy (DOSY) can be used to determine the apparent molecular weight of proteins (Mprotein) by measuring self-diffusion coefficient (Dt-protein). However. Dt-protein is also affected by the property of buffer solution. making the measurements complicated. https://www.lightemupsequences.com/hot-mega-Esko-Nexus-HeightMaster-Vented-Safety-Helmet-big-savings/
