Supplier: Merck

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

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

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

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.

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

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.

Avantor® ACE® C4 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.

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® 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.

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.

Le colonne in PP ultra pulite con supporto HPLC BAKERBOND® sono progettate per risparmiare tempo, minimizzare i volumi di lavoro e di solvente finale e migliorare le prestazioni. Tempi ciclo fino a nove volte più veloci rispetto alle colonne convenzionali. Il filtro di protezione della colonna incorporato e la maggiore concentrazione dell'analita possono ridurre o eliminare le fasi di prefiltrazione e concentrazione.

Supplier: Avantor

Queste colonne sono dotate di resine polimeriche BAKERBOND® DVB, che sono il prodotto della tecnologia delle microparticelle polimeriche ultra pulite. Queste particelle di resina hanno una grande area superficiale, sono altamente rigide, sono stabili nell'intervallo di pH da 1 a 14, sono bagnabili in acqua e non sono influenzate dall'essiccazione del sorbente. Queste colonne sono raccomandate quando si utilizzano metodi di rilevamento avanzato.

Supplier: Avantor

Le colonne BAKERBOND spe™ sono colonne monouso in PP o vetro preconfezionate con sorbenti ad alta capacità contenuti tra due fritte in PE da 20 µm.

Supplier: Avantor

Questa colonna di estrazione in fase solida è progettata per l'estrazione e la pulizia degli idrocarburi poliaromatici (PAH) dal terreno, compresi i 16 PAH inquinanti prioritari dell'EPA e per diverse applicazioni che utilizzano diverse colonne SPE.

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.
