HELIX Chromatography Amaze AR is a stationary phase with a long alkyl chain and a substituted aromatic ring at the end of the alkyl chain. The stationary phase has several polar-embedded groups for enhanced selectivity and for better stability in highly aqueous mobile phases. Highly reproducible and stable in 100% organic and 100% water. Designed to separate aromatic compounds based on specific p-p, and dipol-dipol interaction between analytes and substituted aromatic ring. Suitable for separation of structural isomers of aromatic compounds. Retains hydrophobic non-aromatic compounds based on pure reversed-phase interactions. Can be used as an alternative approach when a difference from pure reversed- selectivity is desired/required. Interact differently with analytes with electron-withdrawing and electron-donating groups. Available in 3µm, 5µm, and 10µm particles.
