This figure shows relation between polarity parameter and retention performance. ODP2 HP was compared with 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 good advantage of analysis of high polar substances.
