Several (metallo)porphyrins, particularly the porphyrin derivative tetraphenylporphyrin, and complexes of porphyrin derivatives with metal ions (Zn 2+ , Cu 2+ , Ni 2+ , Co 2+ , Co 3+ ) have been employed as the stationary phase physically adsorbed onto the inner fused-silica capillary surface for open-tubular capillary electrochromatography, and applied for the separation of structurally related peptides, derivatives of the B23-B30 fragment of the B-chain of human insulin.
