Chromolith® RP-8 endcapped HPLC columns
In contrast to the most commonly used reversed-phase columns the Chromolith® RP-8 endcapped HPLC columns with its shorter alkyl chain offers less retention and a slightly different selectivity. Therefore it is possible to achieve a baseline separation on the RP-8 endcapped bonded column. No separation at all is observed under identical elution conditions on a RP-18 endcapped bonded silica column.
