摘要：

Carrageenans play an important role in many medical and food technology applications. However, the study of their properties has been hampered by a lack of well-defined samples (fractions). In this paper, a new principle is presented by which well-defined fractions can be obtained. It is based on batch adsorption to DEAE-cellulose combined with careful control of temperature and salt content. The parameters have been pre-optimized in an analytical column.
