Abstract
Official abstract text for this publication.
A method for chromatographically separating a first saccharide from a liquid eluent comprising the first saccharide and a second saccharide by passing the liquid eluent through a bed including a polymeric macroporous alkylene-bridged resin in calcium form.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for chromatographically separating a first saccharide from a liquid eluent comprising the first saccharide and a second saccharide by passing the liquid eluent through a bed comprising a polymeric macroporous alkylene-bridged resin in calcium form; wherein said polymeric macroporous alkylene-bridged resin comprises pores having diameters greater than 200 Å and a macroporosity which is greater than 70% of a total pore volume. 2. The method of claim 1 wherein the resin as a surface area of from 300 to 2100 m 2 /g. 3. The method of claim 1 wherein the resin as a surface area of from 450 to 700 m 2 /g. 4. The method of claim 1 wherein the resin has a ratio of alkylene bridging to phenol of from 0.1 to 0.9:1. 5. The method of claim 1 wherein the resin has a ratio of alkylene bridging to phenol of from 0.6 to 0.8:1. 6. The method of claim 1 wherein the total pore volume of the resin is from 0.75 to 0.90 cm 3 /g. 7. The method of claim 1 wherein the resin is provided in bead form having a median diameter of from 100 to 1000 microns. 8. The method of claim 1 wherein at least 90 volume percent of the beads have a particle diameter from about 0.9 to about 1.1 times the volume average particle diameter. 9. The method of claim 1 wherein the first and second saccharide comprises glucose and fructose, respectively.
