    Abstract

    Capillary zone electrophoresis was tried for analyzing water-soluble fiber-tip pen inks from documents. The separation process for the compounds—most of them move as anions—is usually less than 10 min. Some examples of possible applications, also combined with thin-layer chromatography, are given.
