Speciation of Cr as part of biomolecules consists in applying well known biochemical procedures, such as gel permeation chromatography, anion - cation chromatography, affinity chromatography, capillary electrophoresis, ultrafiltration, to be followed on the one hand by the determination of the exact amount of a specific protein and on the other hand by the quantitative determination of the chromium present in the fractions (Cornells, 1990). This is not an easy task. All the commercially available buffers are unfortunately loaded with Cr. The separation medium (e.g. the gel) may be another possible source of error. The contaminating Cr atoms are liable to form fortuitous bindings with the proteins which possess many free ligands.
