Capillary zone electrophoresis (CZE) is one of the novel separation techniques, being applicable, for example, to virtually all important biomass-derived monosaccharides. However, in spite of this fact the utilization of this technique in the pulp and paper industry is currently rather limited. In this chapter practical guidance and some application examples are given to show how carbohydrate material (polysaccharides, oligosaccharides, and neutral and acidic monosaccharides) in pulps and spent liquors can be analyzed by CZE. Emphasis is placed on sample preparation and separation conditions including comparison with other separation methods, such as gas chromatography (GC) and high-performance liquid chromatography (HPLC), generally used for similar purposes. In addition, a short description of other significant degradation products (e.g. aliphatic carboxylic acids and lignin monomers) formed during delignification (e.g. cooking and bleaching) is given. It is concluded that these low-molecular-mass (LMM) degradation products could also be analyzed effectively by CZE.
