TSKgel ODS-100V/ODS-100Z columns incorporate the best-inclass surface properties to limit secondary interactions of basic, acidic and chelating compounds.

• The ultra purity Type B base silica contains negligible amounts of metal ion impurities, minimizes sample adsorption
• High surface area (450 m²/g) silica
• Spherical 3 and 5 µm particles with 10 nm (100 Å) pores
• Very high column efficiency and moderate column back pressure
• Monomeric bonding chemistry
• Low residual silanol content

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.

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.

Both 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.

These columns used for analysis of water and lipid soluble vitamins, organic acids, polymer additives and nucleotides (mono, di and tri).
