MilliporeSigma™ Supelco™ apHera™ NH2 HPLC Column, 5 μm Particle Size

Description

• apHera™ amino columns are based on covalently bonded polyamine specifically optimized for the separation of mono- and oligosaccharides
• The elution order mono-, di-, tri-saccharide shows increased eluton volume with increased acetonitrile concentration and complete stability for both acidic and alkaline eluates
• The small, robust PVA copolymer bead provides mechanical and chemical strength as well as high column efficiency
• Conventional camion columns based on silica do not show long column life, perhaps due to hydrolysis of silica particle by the basic amino group
• Since Supelco uses a strong alkaline compatible polymer, these problems are eliminated
• Stable retention time and long column life are also characteristic of the column.Features of Amino apHera™ Columns
• High efficiency for carbohydrate analysis
• Ideal for basic conditions/amphoteric detection
• High selectivity mono- to oligosaccharides
• pH range 2-13
• 300 angstrom pore size
• Stable, predictable retention
• Long column life.
