These HPLC columns are packed with polymeric, nonporous, ion exchange particles and are designed for high resolution, high recovery and highly efficient separations of peptides, oligonucleotides and proteins.

Supplier: Restek

Highly base-deactivated spherical silica manufactured by Restek. Cyano bonding. Suitable for analyses of a wide range of compounds, from acidic through slightly basic. Also useful for confirmation of analyses on a C18 or C8 column. Can be used in normal phase or reversed phase mode of separation.

Supplier: Agilent

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.

Ultra IBD is a polar-embedded column that acts as a strong hydrogen bonder. With a unique polar group this column is very retentive and selective for acids. It also provides symmetrical peak shape for strong bases. This columns are compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

Supplier: Restek

Viva C8 columns are conventional monomeric octylsilane columns offering a shorter alkyl chain to provide less hydrophobic retention and improved basic peak shape over a traditional C18 phase. These general-purpose C8 columns are suitable for a wide range of compounds from acidic through slightly basic.

Supplier: Agilent

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: Restek
