The pulse tests were performed to understand temperature effect on retention time of sugars and the results were not shown large change. As it was able to predict with PVP resin not to be used for sugar separation generally, the results were shown poor resolution for separation of sugars and temperature effect on the resolution change of sugars also was not large. On the other hand, in the case of organic acids on PVP resin, the pulse tests were shown temperature effect on the retention behavior was very large. So, the frontal analyses were performed to understand quantitative adsorption behavior of organic acids at 35 and 65 o C. These adsorption characteristics of organic acids with PVP resin system can be used to preparative chromatographic process such as SMB (simulated moving bed).
