L-Lysine is an essential amino acid required for growth and tissue repair, it can also help with anxiety. The amino acid is most often found in red meats,beans, fish, and dairy products. L-Arginine is an essential amino acid that is used to treat congestive heart failure, combat fatigue and circulatory diseases. It is also used to stimulate the immune system. Obelisc R is a reverse-phase column. It contains embedded ionic groups and can retain L-Lysine and L-Arginine. The method is UV compatible and can be used as a general approach for analyzing similar compounds.

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.
