GreenSep Amino Phenyl is a specialty SFC stationary phase that has proven superior to conventional stationary phases in the areas of separation selectivity and loading capacity which was designed for the separation of amines, alcohols and acids by SFC without the use of additives. Works well in Normal Phase mixed mode offering pi-pi interaction and exhibits good base deactivation.
Epic HILIC-HC (HC for high capacity) is a new stationary phase for HILIC chromatography. It is composed of a polyhydroxylated polymer coated and 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-HC is specifically designed for HILIC chromatography and can achieve high performance separations, yield rugged methods and deliver long column life times.
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.
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 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.
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 HILIC-PI is a new stationary phase for HILIC chromatography. It consists of an aromatic amine based stationary phase bound to silica. This composition provides for excellent retention and peak shape for polar amine compounds. Many of the commercially available HILIC stationary phases are converted normal phase columns. These normal phase columns yield poor methods, poor separations and lack durability. Epic HILIC-PI is specifically designed for HILIC chromatography and can achieve high performance separations, yield rugged methods and deliver long column life times. Epic HILIC-PI is an excellent choice for samples containing polar amines were superior retention and peak shape are essential.
Epic Biphenyl is a truly unique stationary phase with properties significantly different than ODS phases. This unique character results from bonded biphenyl group 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, nitro aromatics and conjugated systems.
