Abstract
The amino acid taurine (2-aminoethanesulfonic acid) is present as a nutritional supplement in many sports drinks. An experiment, suitable for a junior-senior level instrumental analysis course, is described to measure the amount of taurine in these sports drinks. A pre-column derivatization with Sanger's reagent, 2,4-dinitrofluorobenzene, is followed by an HPLC separation utilizing a gradient elution, and detection at 360 nm.
Supplement
Detailed instructions and questions for students and notes for the instructor are available.
