The aim of this study was to setup a method for detection and quantification of mono saccharide components in technical galactoglucomannas from spruce wood using capillary zone electrophoresis (CZE). CZE technique was optimised regarding borate buffer concentrations, EOF modifier application, and system pH. On the basis of this research, it was concluded that the capillary zone electrophoresis is an efficient analytical procedure for the characterisation of galactoglucomannans derived from softwoods.
The adsorption behavior of fucoidan as well as chitosan derivatives (chitosan sulfate) on PET model film surface was studied using the quartz crystal microbalance technique. Model PET films were prepared by the spin coating technique. The surface chemistry and morphology of the PET-H films was analyzed using XPS and AFM. It was found that chitosan/fucoidan films were thinner and more compressed, while in the case of chitosan/chitosan sulfate, large amounts of chitosan sulfate were adsorbed, indicating a loose and thick adsorbed film.
