MilliporeSigma™ Supelco™ apHera™ C8 HPLC Column, 5 μm Particle Size

Description

• apHera™ reversed columns were devoloped specifically to provide the superior advantages of both silica and polystyrene columns, without the disadvantages of either
• This was accomplished using a vinyl alcohol copolymer base that keeps the surface wetted even with high carbon loads
• The porous structure has an average pore diameter large enough to produce ideal results for small analytes, peptides and small proteins
• These columns equal silica based columns in separation efficiency with organic solvents but provide efficiency with buffered alkaline solutions not possible on silica
• One of the most significant features is logicial elution order of alkylated bases where retention increases proportionately with increasing chain length.Features of apHera™ Reversed Phase Columns
• Stable vinyl copolymer base
• Stable pH range 2-12
• 300 angstrom pore size
• Stable in all organic solvents
• Expanded applications: peptides, proteins
• Efficient separation of any basic substance
• Amenability to washing and alkaline solutions
