ReproSil Amid-C18 ABZ from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a polar-embedded amid-C18 bonded phase and an ABZ (Acid-Base stable) surface modification. This advanced bonding technology combines strong hydrophobic retention from the C18 chain with polar interactions from the embedded amide group, delivering enhanced selectivity for polar, basic, and aromatic analytes while maintaining stability across a wide pH range. The ABZ treatment increases resistance to hydrolysis under acidic and basic conditions, extending column lifetime and ensuring consistent performance in demanding analytical environments.
ReproSil Amid-C18 ABZ columns from Dr. Maisch HPLC GmbH deliver maximum selectivity, aqueous stability, and pH robustness – the ideal solution for challenging reversed-phase HPLC applications.
