Supplier: Thermo Fisher Scientific

Reversed phase columns provide the advantages of high resolution at high flow rates for fast protein separation and analysis.

Supplier: HAMILTON BONADUZ

PRP-h5 polimeric reversed phase columns are ideal for applications that require a high degree of column-to-column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-h5 has no stationary phase coating. The integral reversed phase characteristics of the PRP-h5 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns. PRP-h5 columns are packed with a poly(styrene-divinylbenzene) material.

Supplier: YMC

ODS-AQ is a C18 reversed phase silica based HPLC packing material specifically designed for use in 100% aqueous eluents.

Supplier: Thermo Fisher Scientific

A high performance aminopropyl phase that gives excellent chromatographic properties in three modes: Weak anion exchange, reversed phase and normal phase.

Supplier: CHIRAL TECHNOLOGIES

These protein-based columns are suitable for separation of basic, acidic and non-protolytic compounds. These columns function entirely in the reversed phase chromatographic mode, using buffers with low organic modifier content and at moderate pH values.

Supplier: WATERS

XTerra® MS C18 columns are general purpose, hybrid-based, reversed phase C18 columns that are designed to be compatible with mass spectrometry applications. These first generation columns provide superior pH stability compared to a silica based column.

Supplier: Resonac

These are polymer-based columns, with similar polarity to that of ODS columns have general purpose use.

Supplier: Thermo Fisher Scientific

High density, monolayer C18 reversed phase columns for very good resolution in a variety of applications.

Supplier: PHENOMENEX

These columns have phenyl group bound to the organo-silica surface using a 6-carbon chain for a low bleed aromatic selective phase.

Supplier: CHIRAL TECHNOLOGIES

These columns have the same coated chiral selector as found in the normal phase stationary phases, however in comparison, they use a different bounded silica as the base material which stabilises the CSP.

Supplier: VARIAN

The PLRP-S family of products consists of a range of pore sizes and particle sizes, all with identical chemistry and fundamental adsorptive characteristics. The particles are inherently hydrophobic so there is no bonded phase, alkyl ligand required for reversed-phase separations. This gives a highly reproducible material that is free from silanols and heavy metal ions. Within the extensive product range are columns suitable for analytical separations and preparative purifications.

Supplier: WATERS

Spherisorb® is a porous, spherical material with a range of narrow particle and pore size distribution resulting in very efficient chromatographic separations. These columns have industry standard, fixed end-fittings and are available in three particle sizes. For guard columns, use corresponding Spherisorb® guard cartridge with stand-alone holder listed under “Fittings and Accessories'”

Supplier: PHENOMENEX

This is a high loading, organo-silane particle column. The patented procedure creates a surface that is a strong hydrogen donor and accepter. It is ideal for acids and bases.

Supplier: AGILENT HEWLETT PACKARD

These HPLC columns are made with type A silica. They are useful for many applications of acidic or neutral compounds. These columns have a higher activity level and are therefore useful for separating isomers or other compounds where silanol activity enhances selectivity.

Supplier: PHENOMENEX

C8 column provides less hydrophobic retention than C18, but the density of the ligand bonding creates more steric based selectivity. The C8 columns are generally better hydrogen bond acceptors and better for acidic compounds.

Supplier: AGILENT HEWLETT PACKARD

Poroshell 300 columns are ideal for fast separations of proteins and peptides because the superficially porous particle allows for fast flow rates to be used while maintaining sharp, efficient peaks. Peptides and proteins are typically separated slowly to reduce the potential peak broadening of these slow diffusing analytes. However, Poroshell columns use a superficially porous particle made with a thin layer of porous silica on a solid core of silica, reducing the diffusion distance for proteins making practical rapid HPLC separations of peptides and proteins up to 500 to 1000 kDa.

Supplier: HAMILTON BONADUZ

PRP-1 polymeric HPLC columns are designed for broad ranging uses, similar to C8 or C18 HPLC materials. They combine the best characteristics of silica-based and polymeric columns resulting in highly inert and long-lasting columns. These columns are ideal for applications that require a high degree of column to column and batch to batch consistency (quality assurance, clinical trials). Unlike C8 or C18 columns, PRP-1 has no stationary phase coating. Since there is no stationary phase to hydrolyse, the column maintains its performance characteristics longer than many C8 or C18 columns.
