ES Industries is pleased to introduce a line of Epic 1.8µm HILIC HPLC columns for use with ultra high pressure liquid chromatographs. 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.
