The standard flow rate of the packed column GPC FP-2002 for organic solvent-based SEC (GPC) is 10 mL/min. We have investigated the flow rate dependency of phthalate esters recycling separation. Even at the maximum usable flow rate of 20 mL/min, there is no extreme drop in column efficiency and further speeding up is possible.
(Note) In the case of a polymer sample, molecular chain breakage tends to occur as the molecular weight increases. It is recommended to lower the flow rate, if there is a possibility that chain scission has occurred.
