Molar Mass and Size Distributions

For many products the size and molar mass distributions has a huge impact. Size and molar mass may affects the viscosity of solutions, the adsorption properties, influence uptake and many more. For technical applications it is often needed to control if there is microgels or particulates in samples which may otherwise interfere with the function or the visual properties of the product. At SOLVE we use DLS, SEC-MALS, AF4-MALS and AUC to determine molar mass and size distributions. We are used to working with everything from small peptides and proteins up to large polymers, polysaccharides and nanoparticles. We are often approached with compounds that are challenging to characterize with standard analytical and physio-chemical techniques.
