Avantor® ACE® CN-ES combines CN polar selectivity with enhanced hydrophobicity, enabling the benefits of both interactions to be fully exploited. Extra phase stability and increased column lifetime is provided by an extended alkyl chain spacer between the silica surface and cyano group. Avantor® ACE® CN-ES is suitable for both reversed phase and normal phase separations.

Supplier: Avantor

Vydac MS columns are a later development from Grace for the reversed phase HPLC separation of biomolecules.

Supplier: TOSOH Bioscience

These columns are designed for GFC of water soluble organic polymers, polysaccharides, oligosaccharides, DNA and RNA. They are based on a hydrophilic polymethacrylate matrix, which is stable from pH 2 to 12 and in aqueous eluents with up to 50% polar organic solvent.

Supplier: Thermo Fisher Scientific

HyperSep™ Retain™ PEP polymeric SPE material is a high purity, highly porous polystyrene DVB (divinyl benzene) material modified with urea functional groups to give balanced retention of polar and non polar analytes. HyperSep™ Retain™ PEP is ideal for a wide range of applications, such as drugs and metabolites in biological fluids, peptides in serum, plasma or biological fluids and environmental fluids.

Supplier: Resonac

Robust polymer-based HILIC column for separation by size/chain length.

Supplier: Cytiva

PD-10 Desalting Columns contain Sephadex G-25 resin for rapid buffer exchange, desalting, and removal of small contaminants (salts, dyes, radioactive labels) from samples using gravity flow or centrifugation.

Supplier: Avantor

Everest columns have unique selectivity and sensitivity, which are the result of bonding technology that improves C18 surface coverage and deactivates residual silanols. Previously, the 300 Å C18 chemistries had carbon coverage in the 2,8 to 3,6 µmol/m² range. Everest C18 coverage is in excess of 4 µmol/m² and approximates the theoretical limit based on surface area. The increased shielding of the base silica increases column lifetime and reduces the amount of TFA required to shield the silica.

Supplier: MACHEREY-NAGEL

NUCLEODUR® C18 Pyramid is an octadecyl modified silica phase with polar endcapping, especially designed for use in eluent systems of up to 100% water.

Supplier: VARIAN

Polaris™ amide C18 has the greatest polarity of the Polaris™ C18 family. The amide polar groups offer a different selectivity from either the C18-A or C18-ether phases. The surface has been covalently modified with alkyl amide groups and endcapped.

Supplier: MICROSOLV

Cogent Amide™ has an amide functional group bonded to the silica-hydride surface direct silicon-carbon bonds. Since the ligand is attached to the surface with direct silicon carbon bonds the bonded phase does not hydrolyze in acidic conditions. Also, it does not make a strong association with acetone.

Supplier: Avantor

Vydac TP is the first range of wide pore media phases developed in the Vydac range and it is the industry's standard for peptide and protein separations. The large pores of the 300 Å TP silica give polypeptide molecules complete access to the interior of the silica pores.
