The plasma proteins contained in a plasma solution thereof are chromatographically fractioned, e.g., to obtain a high purity therapeutic grade albumin product, by successively contacting said plasma solution with at least one anion exchanger and at least one cation exchanger in fixed bed chromatography columns, the contact and exchange medium of chromatography therein also comprising a plurality of at least partially hydrophobic support particulates and a plurality of hydrophilic ion exchanger support particulates.

Fractionation/purification of plasma by ion exchange chromatography

A process for purifying sugarcane juices by contacting the juices to be purified in succession with a hydrophobic adsorbent, a supported strong anion exchange material or a hydrophobic adsorbent having anion exchanger groups, an anion exchange resin, and a cation exchange resin. The process may be used to purify low-grade sugar solutions. The process may be used in the sugar industries to obtain sugar syrups, sucrose, aconitic acid, and amino acids.
