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.

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

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

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: VWR Collection

These ELSD models combine simplicity, reliability and robustness for all your analyses or purifications. They allow for the detection of essentially all compounds. Detection is based on a universal property of all analytes, and does not require the presence of a chromophoric group, electro-active group, etc. Control of the system can be done either locally or via a PC. A remote shutdown mode is also provided to minimise cost and enhance system lifetime.

Supplier: Avantor

Very popular nitroterephthalic-acid-modified polyethylene glycol (PEG) column of high polarity for the analysis of free fatty acids, phenols, alcohols, glycols.

Supplier: Avantor

Ultra-clean, PP columns with BAKERBOND® HPLC media are engineered to save time, minimise work and final solvent volumes and improve performance. Run times are up to nine times faster than conventional columns. The built-in column guard filter and higher analyte concentration may reduce or eliminate pre-filtration and concentration steps.

Supplier: Avantor

These columns feature BAKERBOND® DVB polymer resins, which are the product of ultra-clean polymer microparticle technology. These resin particles have a large surface area, are highly rigid, are stable over pH range 1 to 14, are water-wettable and are not impacted by sorbent drying. These columns are recommended when advanced detection methods are used.
