FluoroSep-RP Octyl
Unique Reverse Phase Interaction – FluoroSep-RP Octyl contains bonded perfluorooctyl groups and were designed to separate closely related structural isomers. FluoroSep-RP columns resolve many compounds of pharmaceutical and agricultural interest, especially halogenated molecules. The perfluorinated stationary pyhase is less hydrophobic than a C8 or C18, with a unique selectivity to achieve difficult separations with simple isocratic mobile phases.
FluoroSep-RP Phenyl
FluoroSep-RP Phenyl is a truly unique stationary phase with properties significantly different than ODS phases. This unique character results from bonded pentafluorophenyl groups imparting a pi-pi electron interaction which produces an enhanced retention for many compounds particularly those that contain polarizable electrons. Many classes of compounds contain polarizable electrons including halogenated compounds, aromatics, and conjugated systems. Many naturally occurring chemicals also contain polarizable electrons and can be separated using FluoroSep-RP Phenyl.
FluoroSep-RP Phenyl HS
FluoroSep-RP Phenyl HS is a high surface area ersion of FluoroSep-RP Phenyl and is a truly unique stationary phase with properties significantly different than ODS phases. This unique character results from bonded pentafluorophenyl groups imparting a pi-pi electron interaction which produces an enhanced retention for many compounds particularly those that contain polarizable electrons. Many classes of compounds contain polarizable electrons including halogenated compounds, aromatics, and conjugated systems. Many naturally occurring chemicals also contain polarizable electrons and can be separated using FluoroSep-RP Phenyl.

RingSep
One of the most exciting breakthroughs in HPLC columns for petroleum analysis was the development of the ES Industries RingSep column. The RingSep column was developed specifically for the separation of aromatic compounds by ring number. This column has been optimized to ensure the accurate analysis of aromatic ring distribution. The RingSep column is particularly useful in several areas including petroleum refining, petrochemical production, alkyl aromatic detergent products, and environmental analysis. The RingSep column is also produced in a special version for ASTM Method D5186 for SFC analysis of diesel fuels.
