Size-exclusion chromatography (SEC) of branched polymers and polysaccharides
Branched polymers are among the most important polymers, ranging from polyolefins to polysaccharides. Branching plays a key role in the chain dynamics. It is thus very important for application properties such as mechanical and adhesive properties and digestibility. It also plays a key role in viscous properties, and thus in the mechanism of the separation of these polymers in size-exclusion ch...
متن کاملSize Exclusion Chromatography of Polymers
In the characterization of polymers, size-exclusion chromatography (SEC) has become a standard technique for determining molar mass averages andmolar mass distributions (MMD) of polymers. The principle of SEC is easily understood: owing to limited accessability of the pore volume within the particles of the column packing, polymer molecules are separated according to their hydrodynamic volumes,...
متن کاملSize-Exclusion Chromatography of Polysaccharides with Pulsed Amperometric Detection (PAD)
INTRODUCTION Size-exclusion chromatography is used in carbohydrate research to determine molecular weight distributions of polysaccharides. A variety of detection methods have been used, among them viscometry, lowangle laser light scattering (LALLS), refractive index, ultraviolet/visible absorbance, fluorescence, and precision differential refractometry coupled with ultraviolet detection.This a...

متن کاملExtraction and separation of polysaccharides from Laminaria japonica by size-exclusion chromatography.
A large number of studies have suggested that polysaccharides, such as fucoidan and laminarin, in various seaweeds have significant biological properties. A different distribution of molecular weights is a prominent sign of many polysaccharides. Therefore, a simple, fast and reliable high-performance size-exclusion chromatography (HPSEC) method was proposed to separate fucoidan and laminarin fr...
