Polystyrene standards were analyzed using GPC HK-406, an organic SEC (GPC) column for ultra-rapid analysis. Comparing the separation between an HK-406 with a conventional SEC column of equivalent at the flow rate of 1.0 mL/min, HK-406 achieved the same level of separation with 1/6 analysis time. However, when higher separation is desired, the use of a lower flow rate is recommended.
