Effect of Flow Rate (2) (KF-402.5HQ + KF-403)

The effect of flow rate was examined for organic solvent SEC (GPC) semi-micro columns, GPC KF-402.5HQ and KF-403HQ. Improved separation is observed at lower flow rate, especially for the analysis of large MW compound such as EPON1001.
Please refer to Effect of flow rate (1) (KF-402HQ) for an additional information.
