Chromatography is a technique for the separation of a mixture and is widely practiced in different chemical fields. The mixture is dissolved in a fluid called the mobile phase, which carries it through a column holding another material called the stationary phase. The different partition coefficient of the various constituents in the mixture results in differential retention on the stationary phase, causing them to separate. However, when it comes to mass production, several drawbacks with this technique raises cost significantly.

In the Aquavan Group we use Simulated Moving Bed technology (SMB). By altering the arrangement of the columns, we lengthened the stationary phase indefinitely, and allow the feed entry and analyte recovery to function simultaneously and continuously. With this technology, we can greatly reduce the cost and achieve economical mass production.
