The resolution of the two peaks is between 0.83 and 1.11. There is no particular interaction between xylooligosaccharides and Bio-Gel P-2, and the molecular weight is the dominant factor governing the separation in this system. The purity of xylobiose to xylohexaose separated by once time is 86.94%, 82.90%, 88.30%, 64.20% and 77.89 %, respectively. xylooligosaccharides, gel permeation chromatography, polyacrylamide gel, separation
