Chromolith HPLC

Chromolith® RP-8 endcapped HPLC columns

Chromolith® RP-8 endcapped HPLC column

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.

 

 

Benefits in working with Chromolith® RP-8 endcapped HPLC columns
  • High throughput at high flow rates with the best overall column quality
  • The possibility to use flow gradients
  • Added column performance by column coupling
  • A rigid structure for a longer lifetime
  • Lower matrix sensitivity
