ReproSil pHoenix is a reversed-phase HPLC column series from Dr. Maisch HPLC GmbH, specifically engineered for long-term stability under extreme pH conditions. Built on ultra-high-purity, fully porous silica with special surface modification and bonding chemistry, these columns offer robust performance from pH 1 to 12, making them ideal for the analysis of acidic, basic, or ionizable compounds in challenging mobile phase environments.
ReproSil pHoenix columns are available in standard reversed-phase selectivities such as C18, and are suited for both analytical and method development tasks where column durability and retention reproducibility are critical.
ReproSil pHoenix columns from Dr. Maisch HPLC GmbH deliver exceptional chemical stability and selectivity – ideal for high-performance HPLC applications where pH tolerance and reproducibility are essential.
