[Identification of dextrans using rapid fluid chromatography]. / Kennzeichnung von Dextranen durch schnelle Flüssigchromatographie

It is reported about an analytical method for routine control of clinical dextrans, a method which is considerably quicker than the previously used ones. It is based on the application of HPLC (high pressure liquid chromatography) to permeation chromatography of dextrans on controlled pore glass beads (CPG). The time required for a permeation chromatogram of a dextran sample could be reduced to less than one hour. Calibration curves, necessary for the evaluation of the chromatograms, were established by use of Pharmacia-Testdextrans.
