In order to find out excellent liquid chromatographic clean-up material for rapid PCB analysis, we examined here the separation characteristics of PCB and insulating oil for polymer gels, reversed-phase silica gels, normal-phase silica gels, carbon material and ion-exchange material. Among the various materials examined, the polymer gels were found to give rather high separation performance. Especially, the poly (hydroxymethacrylate) gel could separate PCB completely from insulating oil. However, under the present condition, poly (hydroxymethacrylate) gel required rather long time for PCB separation. Thus, polyvinyl alcohol gel was confirmed to be most suitable for rapid PCB analysis because of the least quantity of fraction liquid as well as the highest resolution. It is expected that the separation performances of poly (hydroxymethacrylate) gel can be improved further by applying a gradient method.
