Ion chromatography - Wikipedia
Ion chromatography - Wikipedia

Ion chromatography, (or ion-exchange chromatography) separates ions and polar molecules based on their affinity to the ion exchanger. It works on almost any kind of charged molecule—including large proteins, small nucleotides, and amino acids.However, ,ion chromatography, must be done in conditions that are one unit away from the isoelectric point of a protein.

Unfortunately, allowing a previously wetted crossflow membrane to dry usually results in permanent reduction of water permeability. Nevertheless, you can attempt to re-wet the membrane and use it. First, soak the membrane in a 50% alcohol solution for at least 15min (ethanol, methanol, or IPA would be acceptable).
