For regular silica-based stationary phases, exposure to extreme pH (especially basic) will have a negative impact on the chemical stability and therefore column lifetime. However, the silica/organosilane surface of the Kromasil™ Eternity™ platform offers a chemical stability that will secure a long-lasting stationary phase, even under tough pH conditions and higher temperatures.
