Size-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 کاملSize-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 کاملLiposome retention in size exclusion chromatography
BACKGROUND Size exclusion chromatography is the method of choice for separating free from liposome-encapsulated molecules. However, if the column is not presaturated with lipids this type of chromatography causes a significant loss of lipid material. To date, the mechanism of lipid retention is poorly understood. It has been speculated that lipid binds to the column material or the entire lipos...
