A novel core-shell ion-exchange resin (St-60) at a fixed core:shell monomer weight ratio of 40:60 and different degrees of cross-linking (10% and 40%) in the porous shell was prepared. The effect of cross-linking degree (10–55%) for these resins and St-60 (55%) in the porous shell on the separation of carbohydrates was examined under strong alkaline conditions. A mixture of inositol, glucose, fructose, and sucrose was separated using 0.10 or 0.15 mol/L NaOH eluent at flow rates of 0.3–0.7 mL/min. The retention times of glucose, fructose, and sucrose on St-60 (40% and 50% degrees of cross-linking) were shorter than those on the fully porous resin (55% degree of cross-linking). The retention times of these carbohydrates increased as the degree of cross-linking in the porous shell decreased. The theoretical plate number for glucose and sucrose also increased as the degree of cross-linking decreased.
