WebDiffusion-based molecular separation. Diffusion NMR is based on the principle that different-sized molecules possess different diffusivities. This permits vertical separation of molecules by their diffusion constants in a 2D NMR spectrum. Heavier molecules diffuse slower, and thus possess smaller diffusion constants than lighter, smaller molecules. mark notthoffWebPOLYSTYRENE Catalog Number Nominal Weight Average Molecular Weight Mw Suggested Concentration % 26971 2,000 0.25 25169 4,000 0.25 25168 20,000 0.25 25170 80,000 0.10 41984 200.000 0.10 25167 ... mark nothumWebFor a concentration C, the volume per molecule is V=1.66/C.
