Sonoma HILIC
The Sonoma line is an equivalent to Phenomenex Luna™. Sonoma HILIC is equivalent to Luna HILIC. Excellent efficiencies, peak shape and resolution are obtained for virtually all Luna™ HPLC applications. A range of particle sizes offers amazing versatility for capillary and LC/MS to prep and process scale applications. ES Industries has developed a line of Sonoma stationary phases equivalent to Phenomenex Luna stationary phases. The new Sonoma phases include C18, C8, HILIC, NH2, SCX and PFP.
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 Amine
Chromegabond Amine Columns based on aminopropyl bonding provide superior, reproducible separations and long column life with excellent peak symmetry. Can be used as a weak anion exchange material or a polar stationary phase in normal phase chromatography.
Epic HILIC PI Prep
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 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.
Chromegabond Triamine
Chromegabond Triamine Columns based on triamine bonding to provide superior, reproducible separations and long column life with excellent peak symmetry.
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.
