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.
VertiSep™ UPS reverse phase packings are fully endcapped after bonding to cover unreached silanols and improve peak symmetry for basic analytes.
VertiSep™ UPS packings are monomeric bonding resulting in lower column back pressure and high column efficiency to better resolve chemically similar analytes.
VertiSep™ UPS are manufactured by statistic process control of silica synthesis, bonding and column packing. The reproducible column packing method control provides exceptional efficiency, symmetry and reproducible capacity factor.
