Size-exclusion chromatography using core-shell particles.
Size-exclusion chromatography (SEC) is an indispensable technique for the separation of high-molecular-weight analytes and for determining molar-mass distributions. The potential application of SEC as second-dimension separation in comprehensive two-dimensional liquid chromatography demands very short analysis times. Liquid chromatography benefits from the advent of highly efficient core-shell ...
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 کاملOptimization of method for detecting and characterizing NOM by HPLC-size exclusion chromatography with UV and on-line DOC detection.
High-performance liquid chromatography (HPLC)-size exclusion chromatography (SEC) with ultraviolet absorbance (UVA) and on-line dissolved organic carbon (DOC) detectors has been adapted and optimized under various conditions. An enhanced HPSEC-UVA system employing a modified commercially available DOC detector provides a better understanding of the qualitative and quantitative natural organic m...
