High-pH Stable C18 Column for Robust Reversed-Phase Separations
ReproSil pHoenix C18 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column specifically engineered for high-pH stability in reversed-phase applications. Its octadecyl bonded phase is protected with a special surface modification that resists hydrolysis, enabling reliable operation in alkaline mobile phases up to pH 12. This makes it ideal for applications requiring improved selectivity for basic compounds, enhanced method flexibility, and extended column lifetime under harsh pH conditions, all while maintaining strong hydrophobic retention and high efficiency.
ReproSil pHoenix C18 columns from Dr. Maisch HPLC GmbH deliver robust, high-resolution performance under high-pH conditions – the optimal choice for demanding reversed-phase HPLC separations.
