Molecular weight of chitosan can be determined by different techniques such as Gel Permeation Chromatography (GPC), Static Light Scattering (SLS) and intrinsic viscosity measurement. Determination of molecular weight by intrinsic viscosity measurement is a simple method for characterization of chitosan. Dif...

Molecular weight determination of materials which are solid or liquid at room temperature is best achieved by taking advantage of one of the colligative properties of solutions, boiling-point elevation, freezing-point lowering, or osmotic pressure, which depend on the number of particles in solution,...
PURPOSE:To obtain colorless and odorless low-MW chitosan soluble in neutral water, by treating chitosan with an aqueous solution containing sodium chlorite and hydrogen peroxide in specified concentrations. CONSTITUTION:High-molecular weight chitosan (A) of a mol.wt. of 300,000-1,000,000, obtained...
