    HPLC Separation of Epinephrine and Epinephrine Sulfonate

    June 5, 2011


    Epinephrine and epinephrine sulfonate are separated on combination of Primesep 100 and Primesep SB HPLC columns. Primesep 100 column retains epinephrine by combination of reversed-phase and cation-exchange mechanisms. Epinephrine sulfonate is retained by weak reversed-phase mechanism. Due to strong zwitter-ionic nature of epinephrine sulfonate, ionic interaction is not available for this molecule. Compounds can be monitored by UV, ELSD, CAD or LC/MS.

    Condition

    Column Primesep SB, Primesep 100 4.6×250 mm, 5 µm, 100A
    Mobile Phase MeCN/H2O – 70/30%
    Buffer AmFm
    Flow Rate 1.0 ml/min
    Detection UV, 270 nm

    HILIC Separation of Epinephrine and Epinephrine Sulfonate

    August 22, 2008

    Epinephrine (also referred to as adrenaline) is a hormone and neurotransmitter. It is a catecholamine, a sympathomimetic monoamine derived from the amino acids phenylalanine and tyrosine. This method can be used to determine and quantitate epinephrine and epinephrine sulfonate in biological fluids (urine, blood, serum) and drug formulations. Obelisc N columns are used to retain and separate epinephrine and epinephrine sulfonate in mixed-mode hydrophilic interaction chromatography. Epinephrine is retained by the combination of cation-exchange and HILIC mechanisms. Epinephrine sulfonate is retained by HILIC mechanism. Buffer concentration and pH, as well as the amount of acetonitrile, can be used to adjust retention of both compounds. Both compounds can be detected by UV, ELSD and LC/MS. Preparative separation is possible with volatile mobile phases (ammonium formate or ammonium acetate.

    Condition

    Column Obelisc N, 4.6×150 mm, 5 µm, 100A
    Mobile Phase MeCN/H2O
    Buffer AmFm pH 3.0
    Flow Rate 1.0 ml/min
    Detection UV, 270 nm

    Application Column

    Obelisc N

    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.
