Abstract
The preparation of the calcium salt of heparin or of products derived from heparin, such as the low molecular weight fractions obtained by extraction or by partial depolymerisation is described. The process according to the invention is characterised in that the calcium salt of heparin or of its derivatives is prepared by employing ion exchange membranes which, when subjected to an electrical field, allow a cation exchange to be carried out on the sodium heparin in a single stage.
