VertiSep AQS hplc columns
  Products > HPLC Columns > VertiSep™ AQS


   Ultra-high purity spherical silica offer excellent stability,
     efficiency and column-to-column reproducibility
   Stable and strong retention in 100% aqueous mobile phase for
     hydrophilic or polar compounds
   High carbon loading C18 offers high degree of hydrophobicity
   High surface area offers high resolution for gradient elution of
     diffculty separation compounds
   Fully endcapped to improve peak shape
   Monomeric bonding offers low back pressure and high column
     efficiency to better resolve chemically similar analytes.


     VertiSep AQS packings are ultra-high purity silica which contains less amounts of metal ions and sulfate contaminants offer excellent stability, efficiency, column-to-column reproducibility and long lifetime at high and low pH levels at pH 1.5-10.0* and ideal for LC/MS or ELSD application.
     VertiSep AQS packings are stable and strong retention in 100% aqueous mobile phase for hydrophilic or polar compounds such as biomolecules, metabolytes, oligosaccharides, amino acids, small peptides, nucleotides and organic acids.
     VertiSep AQS packings are high surface of 300 m2/g offer high capacity and high resolution for fast gradient elution.
     VertiSep AQS reverse phase C18 packings are high carbon loading of 15% offerring the high degree of hydrophobicity.
     VertiSep AQS reverse phase packings are fully endcapped an show selectivity as conventional C18 phases.
     VertiSep AQS packings are monomeric bonding resulting in lower column back pressure and high column efficiency to better resolve chemically similar analytes.
