Obelisc Columns
SIELC has developed the Obelisc™ columns, which are mixed-mode and utilize Liquid Separation Cell technology (LiSC™). These cost-effective columns are the first of their kind to be commercially available and can replace multiple HPLC columns, including reversed-phase (RP), AQ-type reversed-phase, polar-embedded group RP columns, normal-phase, cation-exchange, anion-exchange, ion-exclusion, and HILIC (Hydrophilic Interaction Liquid Chromatography) columns. By controlling just three orthogonal method parameters – buffer concentration, buffer pH, and organic modifier concentration – users can adjust the column properties with pinpoint precision to separate complex mixtures.
Obelisc™ HPLC columns are the latest, innovative columns from SIELC Technologies, the inventors of Primesep. With multiple patents pending, Obelisc columns are the first commercially available columns with Liquid Separation Cell technology ( LiSC ™). Obelisc R, with reversed-phase characteristics, and Obelisc N, with normal-phase characteristics, separate polar and non-polar compounds using multiple separation mechanisms.
