Reprobond CN is a silica-based HPLC column with a bonded cyano phase, offering versatile performance in both normal-phase and reversed-phase chromatography. The moderately polar cyano groups provide balanced retention characteristics, combining dipole–dipole interactions with weaker hydrophobic retention compared to C18 or C8 phases. This dual functionality makes Reprobond CN an excellent complementary column for method development, providing orthogonal selectivity in pharmaceutical, biochemical, and environmental applications.
Reprobond CN provides versatile retention characteristics and robust performance – the reliable choice for laboratories requiring flexible normal-phase and reversed-phase HPLC separations.
