DL-Histidine has been used to study the fouling behaviour of polyethersulfone ultrafiltration membranes made with different PVP (polyvinylpyrrolidone). DL-Histidine is the mixed isomer of D- and L-histidine. DL-Histidine may be used to evaluate the efficiency of amino acid chiral ligand exchange media and systems and in running buffers for capillary electrophoresis.
