Product Category Description:

For HPLC. These columns are packed with PartiSphere spherical 5µm media which feature a narrow particle size distribution and reproducibility. Typical efficiencies are above 75,000 plates per meter. Dual porosity frit distributes sample evenly across the column cross-section. WVS (Whatman Void Sealing) columns have hand-tightened end fittings, and the integral void sealing system mechanism prolongs column life. PartiSphere spherical media are available in eight 5µm phases.

C8 is recommended for ion pair chromatography. This is an end-capped monomeric phase with a 6% carbon load. Provides high efficiency and rapid mass transfer while maintaining excellent peak shape and stability over a range of aqueous mobile phase compositions.

C18 is designed for selectivity of pharmaceuticals, natural products, food, biologicals, and environmental pollutants. This is a polymeric phase with a 10% carbon load. End-capped for deactivation of silanols to minimize need for ion suppression or pairing agents.

PAC is the medium of choice for carbohydrate separations. This is a polar amino-cyano bonded phase with secondary amine groups for good thermal and chemical stability. Selectivity and rapid equilibrium allow separation mechanisms such as adsorption, reversed phase and weak anion exchange to be used. Extremely fast equilibrium across entire range of solvents from heptane to water.

SAX is designed for the separation of nucleic acids, organic acids and inorganic anions, and is particularly effective for the separation of nucleotides. This is a strong anion exchanger based on quaternary ammonium groups (-NR3+). Stable from pH 1.5 to pH 7.5 when used with a Solvecon solvent conditioning column. Designed to obtain high anion exchange efficiencies and resolution.

SCX is designed for the separation of nucleic acids, amino acids, polyamines, drugs and other cationic species. This is a strong cation exchanger based on aromatic benzene sulfonic acid groups. Stable from pH 1.5 to pH 7.0 when used with a Solvecon solvent conditioning column. Uses chemically and thermally stable Si-O-Si-C bonding.
