Epic Diphenyl
Epic Diphenyl bonded phase, with reduced hydrophobicity produces HPLC columns with novel selectivity, exhibiting increased speed and resolution, utilizes strong dipole‐dipole hydrogen bonding and π‐π mechanisms for different selectivity for compounds containing double bonds or aromatic functional groups. In addition, the diphenyl arrangement of the phase can also contribute to steric selectivity allowing for an additional chromatographic interaction. Epic Diphenyl is also highly selective for proteins with aromatic side chains and may be used as a USP L11 column.
Epic HILIC POH
Epic HILIC-POH a polyhydroxylated material specifically designed for HILIC chromatography that can achieve high performance separations, yield rugged methods and deliver long column life times and is useful for the retention and separation of polar and nonpolar compounds. This composition provides hydroxyl levels that are uniform, reproducible and well above conventional hydroxyl and diol type stationary phases.
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 reten- tion on GreenSep Basic when compared to GreenSep Ethyl Pyridine.
Epic Naphthyl
Epic Naphthyl is a naphthalene based 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 exhibits strong π-π interaction and charge transfer interactions and performs well for diastereomers separations and non-polar compounds. The unique properties of Epic Naphthyl places its selectivity between graphitized carbon and alkyl type stationary phases.
Epic Polar
Epic Polar is a high density C18 packing specifically engineered for the retention of polar analytes. Epic Polar is a reversed phase column that enables highly soluble solutes to fully interact with the bonded hydrocarbon phase, even in pure aqueous mobile phases. Under these highly aqueous conditions, our novel proprietary bonding chemistry allows the bonded chains to remain fully extended in the mobile phase. Epic Polar is a true base deactivated reverse phase column and does not contain any undesirable ion exchange or mixed mode characteristics. Epic Polar can retain highly water-soluble compounds such as small organic acids, water-soluble vitamins, purines and pyrimidines, cathecholamines and other polar compounds.
Epic FO LB
A baseline stabilized alkyl perfluorinated C8 – Epic FO-LB, with low bleed characteristics is well suited to the separation of trace impurities especially for halogenated analytes, lipophilic compounds and environmental samples.
Epic Amine HD
The Epic bonding technology produces columns of superior performance and durability. These performance characteristics result from the high bonding density found in the Epic bonding process.
Epic PFP LB
The Epic PFP-LB is a pentafluorophenyl that has been baseline stabilized and is ready for high performance separations for a number of applications including the separation of natural products, halogenated compounds, aromatics, conjugated compounds and trace impurities in complex matrices. Many of these high performance separations were not possible with existing PFP columns especially in the area of trace impurities where baseline bleed levels were unacceptable.
