GreenSep Basic

GreenSep Basic exhibits a highly basic character and is ideally suited to high performance/high speed SFC preparative chromatography applications of chemicals containing amine groups. The chromatogram shown below contains chemicals that are functionalized with amine and acidic groups and is a prime example of the superior peak shape performance and separation capacity obtainable with the GreenSep Basic column. It also compares GreenSep Basic with GreenSep Ethyl Pyridine showing the superior retention on GreenSep Basic when compared to GreenSep Ethyl Pyridine.

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 Naphthyl

GreenSep Naphthyl is based on the rigid structure of pi electron rich and the naphthalene molecule provides a basis for many diastereomeric separations. A naphthalene based SFC material, with high bonding density and intrinsic base deactivation due to a rigid structure that also enables the shape selectivity needed for many diastereomeric separations. It also exhibits strong π-π interaction and charge transfer interactions and performs well for diastereomers separations and non-polar compounds. The unique properties of GreenSep Naphthyl place its selectivity between graphitized carbon and alkyl type stationary phases.

GreenSep Pyridyl Amide

The type of chemicals separated on a GreenSep Pyridyl Amide column would normally require the addition of TFA or an amine to the mobile phase as a peak shape modifier; however GreenSep Pyridyl Amide does not require this addition. Ideal for chemicals that contain both basic amine and acidic groups, as shown in the chromatogram below, GreenSep Pyridyl Amide provides flexibility for the SFC chromatographer with mobile phase composition and fraction collection greatly simplified without the use of amino additives.
