Representative HPAEC-PAD chromatographic profiles of the chitosan degradation. Chromatograms correspond to the COS mixtures obtained by hydrolysis of chitosan CHIT50.2 after 24 h. Peaks assignation: (1) apparently (GlcNAc)2-(GlcN), (2) (GlcNAc)2, (3) (GlcNAc)3, (*) non-identified. On the right a schematic representation of the polymerization degree and composition of reaction products predicted from MS data (Additional file 1: Table S4) is presented
