Different concentrations of chitosan were prepared and measurement was done at room temperature. To study the effect of radiation on molecular weight, chitosan was first irradiated using electron beam at different doses prior to measurement.

(author)ĭetermination of viscosity-average molecular weight of chitosan using intrinsic viscosity measurement The value of intrinsic viscosity was then recalculated into the viscosity-average molecular weight using Mark-Houwink equation. The flow time data was used to calculate the intrinsic viscosity by extrapolating the reduced viscosity to zero concentration.
Determination of molecular weight by intrinsic viscosity measurement is a simple method for characterization of chitosan. Molecular weight of chitosan can be determined by different techniques such as Gel Permeation Chromatography (GPC), Static Light Scattering (SLS) and intrinsic viscosity measurement.
