As shown in the table, high purities, high concentrations, and high recovery rates were obtained for each respective components in accordance with set goals.
In this fractionation of four components, the separation between sucrose and glucose is accomplished withdrawing in a time lag fractions (B1 and B2) which contain high amounts of each respective component.
In this way, using the New JO Chromatographic Separation System, in principle it is possible to perform multicomponent separations of four or more components.
The Amberlite CG6000 which was used in this test, a strong acid cation-exchange resin in gel form of uniform particle diameter developed for chromatographic separations, is an adsorbent very suitable to fractionations of saccharides.
