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.

Le colonne Avantor® ACE® Silica garantiscono un'elevata riproducibilità e durata della colonna. Queste colonne in acciaio inossidabile sono disponibili in un'ampia gamma di dimensioni e granulometrie delle particelle, da capillari a preparative.

Supplier: Avantor

La fase Avantor® ACE® C18-PFP utilizza un legante appositamente sviluppato che combina una catena C18 con funzionalità completa del PFP. Ciò determina una fase che mantiene le caratteristiche idrofobiche, di stabilità e di basso spurgo delle fasi C18 principali, ma che offre ancora i meccanismi di ritenzione multipli di una fase PFP. Grazie alla funzionalità completa del pentafluorofenile, la fase Avantor® ACE® C18-PFP è ulteriormente raccomandata per separazioni che implicano composti aromatici alogenati, regioisomeri e per analiti con limiti di forma differenti. In acciaio inox.

These 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.

Supplier: Avantor

Avantor® ACE® C18-300 columns provide great reproducibility and column lifetime. These stainless steel columns are available in a wide range of particle sizes and dimensions from capillary to preparative. These columns are designed for a wide range of chromatographic applications, to provide great performance with acidic, basic and neutral molecules.

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

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.

LiChrospher® is a silica available in both endcapped and non-endcapped C8 and C18 phases.

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
