Thermo Fisher Scientific has several phases that are designed for the retention of polar compounds, or offer alternative selectivity to traditional HPLC phases.

AQUASIL C18 capillary columns for chromatography of difficult polar compounds

LC columns for more retention of polar compounds and stability in 100% aqueous.

BETASIL Phenyl/Hexyl columns offer sharp peaks and excellent reproducibility

BetaMax Acid columns with high surface area resulting in maximum retention

BetaMax Base are fully endcapped, with high surface area due to a 60Å pore size

Fluophase columns for retention, selectivity for halogenated or polar compounds

Fluophase columns for retention, selectivity for halogenated or polar compounds

HyPURITY ADVANCE columns are designed for rapid analysis and high sample throughput.

HyPURITY AQUASTAR are ideal for applications involving MS detection

Hypercarb capillary columns are for difficult-to-retain or resolve compounds

A unique porous graphitic carbon HPLC phase for problem separations.

Outstanding performance and unique selectivity with Hypersil GOLD perfluorinated columns

PRISM RPN columns are HPLC columns that are ideal for 0 to 100% organic fast gradients.
