VertiSep™ HCS packings are high purity silica which contains less amonts of metal ions and sulfate contaminants offer high stability at pH 1.5-10.0* efficiency, column-to-column reproducibility and long lifetime.
VertiSep™ HCS reverse phase C18 packings are highest carbon loading of 23% offerring the highest degree of hydrophobicity for highest resolution of organic compounds that have similar structures such as polynuclear aromatic hydrocarbons, benzidines, vitamins D2, D3, PTH and amino acids.
VertiSep™ HCS 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.
