• Ultra performance silica with excellent stability,
efficiency
and column-to-column reproducibility
• Ultra-high surface area offer ultra high resolution for
gradient elution of difficulty separation compounds
• High carbon loading C18 offers the high degree of
hydrophobicity
• Fully endcapped to improve peak shape
• Monomeric bonding offers low back pressure and high
column efficiency to better resolve chemically similar
analytes.

VertiSep™ UPS packings are ultra-high purity spherical silica
which contains less amounts of metal ions and sulfate
contaminants offerring ultra performance with excellent
stability at pH 1.5-10.0*, excellent efficiency, column-to-column
reproducibility, long lifetime and ideal for LC/MS or ELSD
applications.
VertiSep™ UPS packings are ultra-high surface of 450 m2/g
offer greater capacity and higher resolution for gradient elution
of difficult separation compounds like basic drugs, organic
acids and other polar compounds.
