This figure shows the relation between polarity parameters and retention performance. ODP2 HP was compared with the current polymer-based column ODP-50 and other general ODS columns. ODP2 HP shows higher retention of high polar substances compared with other columns. It means ODP2 HP has a good advantage of the analysis of high polar substances.
Columns : Shodex ODP2 HP-4D, Asahipak ODP-50 4D (4.6mI.D. x 150mm) ODS(A), ODS(B) from other manufacturer (4.6mmI.D. x 150mm) Eluent : H2O/CH3CN=75/25 Flow rate : 1.0mL/min Column temp. : 40°C
