Size 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 کاملOrganic matter from biofilter nitrification by high performance size exclusion chromatography and fluorescence excitation-emission matrix
A combination of high performance size exclusion chromatography with organic carbon detector and ultraviolet detector coupled with peak-fitting technique and fluorescence excitation-emission matrix spectrometry applied fluorescence regional integration method was conducted to determine the characteristics of organic matter during nitrification. The batch scale of bionet nitrification without or...
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 کاملHigh Performance Gel Permeation Chromatography of Polymers
The determination of the molecular weight distribution by gel permeation chromatography requires the establishment of a molecular weight calibration and efficient columns in order to minimise chromatogram broadening. The separation process is described in terms of steric exclu— sion, retardation and partial exclusion mechanisms in order to show how the universal calibration method may be influe...
متن کاملOptimization of conditions for high-performance size-exclusion chromatography of different soil humic acids.
A method of high-performance size-exclusion chromatography (HPSEC) for a wide variety of soil humic acids (HAs) was developed. Two types of soil HAs (Cambisol and Andosol HAs), which have substantially different chemical properties, showed different effects of salt and organic solvent concentrations in the eluent on chromatograms. A Shodex OHpak SB-805 HQ column with 10 mM sodium phosphate buff...
