Gel permeation chromatography of the xanthan gum using a light scattering detector

Summary This work gives the first gel permeation chromatogramms obtained on native xanthan using a refractometric and a light scattering detectors. Results of molecular weights distribution analysis give a polydispersity 1.2 for the native polymer and 1.7 for enzymic partially degraded polymer. The experimental conditions and chromatogramms interpretation are briefly discussed.Laboratoire Propre de C.N.R.S., associé à l'Université Scientifique et Médicale de Grenoble
