Comparison of KF-602 and KF-802

Print

Downsized organic SEC (GPC) Column, GPC KF-602 (6.0mmI.D. x 150mm) and standard type column KF-802 (8.0mmI.D. x 300mm) are comapred using styrene oligomer. The required analysis time is 10 min. for KF-602 and 20 min. for KF-802. This means the analysis time for KF-602 is about half of that for KF-802. The solvent consumtion is 6mL (0.6mL/min x 10min.) for KF-602 and 20mL (1.0mL/min x 20min.) for KF-802. This means the solvent consumption for KF-602 is less than one third of that for KF-802.


Sample: Styrene oligomer
