Sieving separations can be accomplished using solutions of linear or branched hydrophilic polymers. These polymers have low UV absorbance at short wavelengths, and can be replenished between analyses by pressure. Polymer solutions act by forming entangled networks above a certain polymer concentration, which mimics the sieving properties of cross-linked gels.
