Avantor® Genesis phases are based on high purity metal-free spherical silica. They are suitable for the analysis of a wide range of analytes.

Supplier: Avantor

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES, are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

Supplier: Avantor

DPTMDS deactivated fused silica retention gap / precolumn. General purpose deactivation for both apolar and polar solvents.

Stainless steel LiChroCART® cartridges are available with various types of Purospher® sorbents.

Supplier: Merck

Stainless steel LiChroCART® cartridges are available with LiChrospher® sorbents. Ideal for separation of compounds under basic eluents.

Supplier: Merck

Stainless steel Hibar® columns are complete with endfittings. These columns are available with various types of Purospher® sorbents.

Supplier: Merck

ZIC®-pHILIC has the same stationary phase as ZIC®-HILIC, but is instead based on a polymeric particle for enhanced pH stability. The lack of silica practically nullifies background in high sensitivity detectors such as charged aerosol used for determination of organic and inorganic ions.

Supplier: Merck

Stainless steel Hibar® columns are complete with endfittings. These columns are available with various types of LiChrospher® sorbents.

EXtrelut® NT is a specially processed, inert, wide pore kieselguhr with a high pore volume. It has been used for quite some time within research, for the sample preparation of urine, whole blood, plasma and other biological matrices. Other applications include environmental and residue testing such as analysis of industrial, domestic and wastewater. EXtrelut® NT is supplied either pre-packed in cartridges or as a loose sorbent. EXtrelut® NT simplifies liquid-liquid extraction by replacing separation funnels. Using a single step is more efficient, saves solvent, as well as material and time, in contrast to classic funnel separation. The aqueous sample is simply applied to the EXtrelut® NT sorbent. It distributes itself over the chemically-inert matrix so acting as a stationary phase. Subsequently, elution takes place using organic solvents that are non miscible with water. All the lipophilic substances are extracted from the aqueous into the organic phase.

Supplier: Merck

Chromolith® Phenyl HPLC columns offer greater selectivity towards aromatic ring-containing compounds than standard alkyl phases. These columns are ideal for the separation of aromatic compounds, flavonoids, fatty acids, PAH, preservatives, purines and pyrimidines.

Supplier: Merck

These bonded poly(5% diphenyl/95% dimethylsiloxane) low phenyl content columns improve thermal stability of the phase, while still providing essentially a boiling point elution order, and a slight increase in selectivity, especially for aromatic compounds.

Supplier: Merck

This Reversed phase Supelclean™ ENVI-18 are suitable for excellent for cleaning, extracting and concentrating pollutants from aqueous environmental sample (drinking, ground, waste water). Also suitable for extracting herbicides, fungicides and pesticides from waste material.

Supplier: Merck

Ascentis® Express 90 Å Phenyl-Hexyl high-speed, high-performance liquid chromatography columns are based on a Fused-Core® particle design.

Supplier: Merck

The Discovery® RP-Amide C16 HPLC Column with unique retention and selectivity.

Supplier: Merck

Ascentis® C8 HPLC columns are optimised to the three terms of the resolution equation: efficiency, retention, and selectivity.

Supplier: Merck

Silica based SUPELCOSIL™ LC-NH₂ columns separate monosaccharides, disaccharides, and some trisaccharides, with elution generally in order of increasing molecular weight. Retention decreases as the proportion of water:acetonitrile in the mobile phase is increased.

Supplier: Merck

Ascentis^® Express ES-C18 is a non-endcapped C18 stationary phase based on the proven Fused-Core^® particle design.

Supplier: Avantor

Avantor® ACE® UltraCore SuperC18 solid core (core shell) particle columns are ideal for demanding MS work offering improved MS signal intensity and maximum MS response. These stainless steel columns combine high efficiency separations with low column back pressure. The Encapsulated Bonding Technology (EBT™) greatly increases the ligand coverage of the silica surface and effectively eliminates the effect of unbonded silanol groups on separations. This higher ligand coverage results in improved inertness, chromatographic performance and stability.

Stainless steel Equivalence C18 columns have been specifically developed as a high quality, cost effective replacement for many HPLC column brands.

Supplier: Avantor

The Avantor® ACE® Excel® C18-AR phase utilises a specially developed ligand combining a C18 chain with integral phenyl functionality, thus combining the benefits of both C18 and phenyl characteristics into a single phase. This can be used for ‘standard’ C18 column separations, but is additionally recommended for separations that involve compounds containing aromatic functionality.

Supplier: Avantor

Avantor® Alltima HPLC columns are high quality phases designed for general purpose applications.

Supplier: Avantor

Avantor® ACE® C18-PFP phase utilises a specially developed ligand combining a C18 chain with integral PFP functionality. This results in a phase that maintains the hydrophobic, stability and low bleed characteristics of leading C18 phases, yet provides the multiple retention mechanisms of a PFP phase.

Supplier: Avantor

Vydac TP was the first range of wide pore media phases developed in the Vydac range and became the industry 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.
