Characterizing Molecular Structure in Synthetic and Natural Polymers by Multi-Angle Light Scattering
Nowadays, in the majority of analyses the standard-calibrated SEC is the method employed for many polymers. However, as this is not an absolute technique, it may deliver wrong results for certain samples. Especially branched and/or exceptionally large-sized molecules have been shown to exhibit abnormal elution behavior which leads to wrong data for molar mass determination.
In this webinar the principles of detection and characterization of polymers will be discussed. It will be elucidated how SEC failures can be overcome using the absolute method of light scattering. This approach also enables to determine branching distribution and calculate average branching ratios. Moreover, the attendants will learn about the advantages of field flow fractionation for the separation of large and branched macromolecules.
