Epic Diol HILIC
Epic Diol HILIC 1.8 um columns have been specifically developed for HILIC chromatography. The combination of tight particle size control and our proprietary high density bonding technology deliver superior performance for HILIC separations.
Epic SCX
Epic SCX is a strong cation exchanger on a silica base. It’s suitable for the analysis of organic bases or as a trap column for two dimensional HPLC. Epic SCX utilizes the high density bonding technology which provides for superior cation loading and robustness. Epic SCX is based on bonded aromatic sulfonic acid groups and is available in 10, 5, 3 and 1.8 um particle sizes. Epic SCX will provide for the best performance of any silica based cation exchanger. Epic SCX has an exchange capacity of 3meq/gram making it the strongest silica based cation exchanger available. A separation of four nucleosides is shown below using only ammonium formate as a mobile phase.
Epic HILIC RP
Epic HILIC-RP is a new stationary phase for a combination of HILIC and reverse phase chromatography. It is a combination of a polyhydroxylated polymer coated and bound to silica and ODS groups also bound to silica. This composition provides hydroxyl levels that are well above conventional hydroxyl and diol type stationary phases. Many of the commercially stationary phases used for HILIC chromatography are converted normal phase columns. These normal phase columns yield poor methods, poor separations and lack durability. Epic HILIC-RP is specifically designed for HILIC chromatography and can achieve high performance separations, yield rugged methods and deliver long column life times. Epic HILIC-RP is an excellent choice for samples containing polar and hydrophobic analytes.
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 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.
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 Phenyl Hexyl
Epic Phenyl-Hexyl uses a hexyl-linked phenyl phase. The hexyl alkyl chain provides for unique selectivity and increased hydrolytic stability when compared to propyl-linked chemistry. The Epic high-density bonding technology delivers to the chromatographer superior performance, durability, and enhanced lot-to-lot reproducibility. Epic Phenyl-Hexyl offers the chromatographer a truly superior phenyl based interaction for enhanced chromatographic performance.
