VertiSep™ GES packings are high purity silica which contains less amounts of metal ions and sulfate contaminants offer high stability at pH 1.5-10.0*, efficiency, column-to-column reproducibility.
VertiSep™ GES packings are moderate pore size and surface area proving general purpose separations of variety of compounds.
VertiSep™ GES reverse phase C18 packings are high carbon loading of 17% offerring the high degree of hydrophobicity for high resolution of organic compounds that have similar structures such as polynuclear aromatic hydrocarbons, benzidines, vitamins D2, D3, amino acids.
VertiSep™ GES 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
