GreenSep™ stationary phases have been specifically engineered for SFC separations paying close attention to bonding coverage, density and all factors leading to high capacity phases which exhibit excellent selectivity and peak shape.

GreenSep 4-Ethyl Pyridine

GreenSep 4-Ethyl Pyridine is an alternative to and provides different selectivity to GreenSep Ethyl Pyridine (2- ethyl pyridine). The chromatogram below shows the separation of chemicals such as ibuprofen, ketoprofen and niflumic acid, without peak shape modifiers, and is a prime example of the superior peak shape performance obtainable with the GreenSep 4-Ethyl Pyridine column.

GreenSep DEAP

Unlike many SFC columns which require the addition of amine modifiers to the mobile phase to improve peak shape for basic compounds, GreenSep DEAP does not, greatly simplifying mobile phase composition and fraction collection. This makes GreenSep DEAP the SFC column of choice for the retention and rapid separation of chemical compounds containing strong amine groups.

GreenSep FluoroBasic

GreenSep FluoroBasic is based on fluorinated imidazole chemistry providing a highly basic and fluorinated character for this stationary phase. The addition of a fluorine groups into this stationary phase can be useful in promoting fluorophilic retention mechanism which can provide improved retention for fluorinated compounds. A fluorophilic retention mechanism can be particular useful in medicinal chemistry and drug discovery, where more than a third of newly approved small molecule drugs contain fluorine.
