HPLC Separation of Aspartic Acid and Asparagine on Obelisc R Column


Two amino acids, aspartic acid and asparagine, are separated on an Obelisc R column by combination of reverse-phase and ion-exchange mechanism. Method can be used for analysis of these and other underivatized amino acids by HPLC with UV, ELSD, CAD and LC/MS detection.

Application Column

Obelisc R

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.
