Stability 120 Amid-C12 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a 120 Å pore size and a polar-embedded amidic C12 bonded phase. The embedded amide group reduces silanol interactions, improving peak symmetry for basic analytes, while the C12 chain provides moderate hydrophobic retention for efficient reversed-phase separations.
Thanks to its enhanced chemical stability, this column performs reliably under extreme pH conditions, aggressive mobile phases, and high-temperature gradients, ensuring long lifetime and high reproducibility in demanding analytical workflows.
Stability 120 Amid-C12 columns from Dr. Maisch HPLC GmbH combine polar-embedded functionality with durable bonding technology – the ideal choice for reliable, high-performance reversed-phase HPLC separations.
