Eurospher II Chiral OM uses the chiral selector Cellulose-tris-(3,5-dimethylphenylcarbamate) and is equivalent to Chiralcel OD.

Eurospher II Chiral NR is an immobilized brush-type phase with very broad generality and orhogonal selectivity to Eurospher II Chiral AM and OM.

Luna Omega Polar C18 is a novel HPLC and UHPLC stationary phase capable of providing a unique selectivity within a wide elution window and increased retention for both polar and non polar analytes.

Luna Omega PS C18 is a unique mixed interaction stationary phase that provides incredibly useful polar and non-polar retention.

The Luna HILIC is a diol based silica phase that allows for an denser aqueous layer for increase polar selectivity.

The Luna Phenyl Hexyl is our most hydrophobic phenyl column and it will also provide good hydrogen accepting functionality for acidic retention.

The Luna CN has Nitrile groups bound to the silica surface which offer a unique polar selectivity under reversed phase or normal phase conditions.

The Luna PFP(2) is a pentafluorophenyl phase with strongly electronegative fluorine groups to provide polar selectivity for cationic compounds.

The Luna C18(2) phase is an octadecyl silane with ligands bound to the silica surface, resulting in a C18 HPLC column with a very hydrophobic stationary phase.

High performance silica and bonding techniques produce a rugged, highly reproducible amino phase.
