Gel permeability chromatography
WebGel Permeability Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), is a chromatographic method that separates molecules based on particle size. This method is used to obtain fast and precise results in the determination of molecular weight and molecular weight distribution of polymers. Instrument: Malvern – … WebThe molecular weight was characterized using gel permeability chromatography multiangle laser light scattering and the composition of the polymer was analyzed using proton nuclear magnetic resonance.Results: The GT–SPE successfully protected the DNA from nucleases. The average particle size of the GT–SPE was 121 nm with a zeta …
