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.
Chromegabond Cyano
Chromegabond Cyano Columns based on cyanopropyl bonding to provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used to separate polar compounds in both reverse phase and normal phase chromatography.
Epic HILIC HC
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.
Chromegabond Amino Cyano
Chromegabond Amino Cyano Columns based on aminopropyl/cyanopropyl bonding to provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used to separate polar compounds in both reverse phase and normal phase chromatography.
ChromegaChiral CC3 Prep
ChromegaChiral CC3 (amylose tris(5-chloro-2-methyl- phenylcarbamate) is a new product for high resolution chiral separations based on a new halogenated carbohy- drate based chiral stationary phase. Similar in selectivity to ChiralPak® AY-H.
Epic HILIC FL Prep
Epic HILIC-FL is useful for retention and separation of polar and non-compounds. Reversed-phase HPLC is widely used for separation of many pharmaceutical compounds. However, retention and separation of many polar analytes has proven to be a challenge. Many of these types of compounds are unretained or poorly retained on most conventional reversed-phase stationary phases, such as ODS. Fortunately, to deal with these types of analytes an alternative mode of chromatography can be utilized using polar stationary phases and highly organic mobile phases. This mode of chromatography has been utilized for many years and is referred to as “hydrophilic interaction chromatography” or HILIC. HILIC chromatography uses mobile phases containing between 5 – 20 % water for the retention of polar compounds.
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.
Chromegabond Cyano BD
Chromegabond CN BD is a specially developed base deactivated CN material. Excellent peak shapes are obtained, without modifiers, through the use of special organosilanes and ultra pure synthetic silica.
