ReproSil Mixed-Mode Amino-C8 from Dr. Maisch HPLC GmbH is a high-purity silica-based HPLC column with a mixed-mode stationary phase combining aminopropyl functionality and octyl bonding. This hybrid chemistry provides polar interaction capability alongside moderate hydrophobic retention, enabling versatile separations for analytes with a wide range of polarities. The medium-chain C8 phase offers faster elution than C18 while retaining sufficient hydrophobic selectivity, making this column ideal for method development where balanced retention and dual-mode selectivity are required.
ReproSil Mixed-Mode Amino-C8 columns from Dr. Maisch HPLC GmbH provide balanced retention with dual selectivity – the flexible choice for complex mixture HPLC separations.
