(1) Prepared by an incomplete first reaction with a difunctional octadecylsilane reagent, which is followed by endcapping with a mixture of two
difunctional dialkylsilane reagents.
(2) Prepared by bonding the surface with a difunctional octadecylsilane reagent, followed by repeated endcapping with monofunctional
trimethylsilane reagent.

TSKgel ODS-100V
&
TSKgel ODS-100Z
columns incorporate the best-in-
class surface properties to limit secondary interactions of basic, acidic
and chelating compounds. The ultra high purity Type B base silica
contains negligible amounts of metal ion impurities.
TSKgel ODS-100V
provides strong retention for polar compounds
due to its lower C18 ligand density (15% carbon content). Proprietary
monomeric bonded phase chemistry provides complete wetting and
retention stability in 100% aqueous mobile phases.
The
TSKgel ODS-100V
and
TSKgel ODS-100Z
column lines were
expanded to include 3 µm packed columns. These columns are well
suited for high throughput LC/MS applications, providing fast and
efficient separations.
TSKgel ODS-100Z
contains a high density (20% carbon content)
monomeric C18 bonded phase for maximum retention and selectivity of
small molecular weight compounds. Exhaustive endcapping prevents
secondary interaction with residual silanol groups.
