Aqueous two-phase systems

Patent Granted Aqueous biphasic systems (ABS) or aqueous two phase systems (ATPS) are clean alternatives for traditional organic-water solvent extraction systems. ABS are formed when 2 polymers, one polymer and one kosmotropic salt, or two salts (one chaotropic salt and the other a kosmotropic salt) are mixed at appropriate concentrations or at a particular temperature. The two phases are mostly composed of water and non volatile components, thus eliminating volatile organic compounds.
