Kromasil® Eternity and Eternity XT can be used in a wider pH window than regular silica-based HPLC materials, giving more flexibility than ever when running analytical applications or optimizing for large-scale applications.

• Proprietary organic/inorganic layer
• pH stable from 1 to 12 (C18) or 2 to 12 (PhenylHexyl)
• Kromasil® Eternity available in 2,5 and 5 mm particle sizes
• Kromasil® EternityXT available in 1,8; 2,5; 5 and 10 mm particle sizes; 1,8 mm suitable for UHPLC instrumentation
• Robust and reproducible

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.
