Retention of Taurine on Obelisc N Column

July 3, 2013

Taurine, or 2-aminoethanesulfonic acid, is a very polar zwitter-ionic compound. Taurine is used as an additive for various nutrition composition. The polar and zwitter-ionic nature of taurine prevent it from analysis by RP chromatography, in addition to that, taurine is not UV active and cannot be monitored by UV. The analytical method for analysis of taurine was developed on the Obelisc N HILIC/mixed-mode column. This method with some modifications can be used for the analysis of taurine in complex mixtures with a ELSD or a LC/MS detector.

Condition

Column Obelisc N, 4.6×50 mm, 5 µm, 100A
Mobile Phase MeCN
Buffer AmFm pH 3.0
Flow Rate 1.0 ml/min
Detection ELSD

 

Description

Class of Compounds
Amino sulfonic acid, Hydrophilic, Ionizable, Vitamin, Supplements
Analyzing Compounds Taurine

 

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.

Taurine, or 2-aminoethanesulfonic acid, is a very polar zwitter-ionic compound. Taurine is used as an additive for various nutrition composition. The polar and zwitter-ionic nature of taurine prevent it from analysis by RP chromatography, in addition to that, taurine is not UV active and cannot be monitored by UV. The analytical method for analysis of taurine was developed on the SHARC 1 hydrogen-bonding column. This method with some modifications can be used for the analysis of taurine in complex mixtures with a ELSD or a LC/MS detector.

Application Column

SHARC 1

The SHARC™ family of innovative columns represents the first commercially available columns primarily utilizing separation based on hydrogen bonding. SHARC stands for Specific Hydrogen-bond Adsorption Resolution Column. Hydrogen bonding involves an interaction or attraction between a bound hydrogen atom and molecules containing electronegative atoms, such as oxygen, nitrogen, and fluorine.

HPLC Method for Analysis of Taurine on Primesep D Column

December 6, 2007

Taurine (2-aminoethanesulfonic acid) is organic zwitterionic compound. Taurine is a non-essential sulfur-containing amino acid that functions with glycine and gamma-aminobutyric acid as a neurotransmitter. Taurine is incorporated into one of the most abundant bile acids, chenodeoxycholic acid, where it serves to emulsify dietary lipids in the intestine, promoting digestion. It is used in food and pharmaceutical formulations. High polarity and zwitterionic nature of taurine complicates analysis of this compound by reverse-phase chromatography. Two methods for the analysis of taurine are developed on mixed-mode columns. Taurine is retained on Primesep A column by HILIC cation-exchange mechanism and on Primesep D column by HILIC anion-exchange mechanism. Method can be used for fast and effective quantitation of taurine in various products including energy drinks. Method requires ELSD or LC/MS detection due to lack of UV activity for taurine.
