Separation examples which
use the New JO Chromatographic Separation System.
Separation of high purity saccharides |
Here is an example where feed, which contained a large quantity of impurities therefore making it difficult to separate, is directly separated into high purity saccharides using the New JO Chromatographic Separation System.
The goal of the separation test using this pilot plant was to separate out the targeted component, a disaccharide called DP2.
The results of this test are compared with those of a test performed using the simulated moving-bed mode and are displayed in the table.
Test Equipment: Inside Diameter of Column 108 [mm] * Height: 1600 [mm] * 10 columns

As shown in the table, we were able to separate out component DP2 at a high level of purity.
This example shows that even those separations which can be done with the original simulated moving-bed mode (i.e. where the absorption affinity of the component DP2 is the strongest), the use of the New JO Chromatographic Separation System results in a separation of higher purity.
In this example, a intermediate fraction having merits for a new market was obtained, and the system itself was adopted for commercial use.
