ReproSil Mixed-Mode Amino-C18

Dual-Function HPLC Column Combining Amino and C18 Selectivity

ReproSil Mixed-Mode Amino-C18 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column featuring a mixed-mode stationary phase that combines aminopropyl functionality with octadecyl bonding. This dual chemistry enables reversed-phase and polar interaction mechanisms within a single column, offering unique selectivity for complex mixtures containing both hydrophilic and hydrophobic compounds. The combination of polar amino groups and hydrophobic C18 chains allows analysts to fine-tune separations, making this column an excellent choice for method development and challenging applications requiring multiple interaction modes.

ReproSil Mixed-Mode Amino-C18 columns from Dr. Maisch HPLC GmbH deliver versatile dual-mode separation capabilities – the ideal choice for complex mixture analysis and challenging HPLC applications.

Key Features:

  • Fully porous, ultra-pure silica with dual amino and C18 bonding

  • Mixed-mode retention: reversed-phase and polar interactions

  • Unique selectivity for complex or diverse analyte mixtures

  • High efficiency and reproducibility for both small molecules and polar compounds

  • Manufactured and QC-tested by Dr. Maisch HPLC GmbH

  • Available in 3 µm and 5 µm particle sizes

Typical Applications:

  • Separation of mixtures containing polar and non-polar compounds

  • Pharmaceutical analysis of APIs and excipients in one run

  • Method development requiring orthogonal selectivity

  • Food, environmental, and natural product analysis
