A method for rapid quantitative determination of free amino acids and several vitamins in i.v. solutions and beverages was developed. The separation was performed on a NH2 column with an acetonitrile/phosphate buffer gradient. The samples, injected without a derivatization procedure, were separated within 30 min. With a time programmable wavelength detector, the required high sensitivity was achieved. The relative SD for quantitative results were 1-2%. Quality and stability testing of i.v. solutions are immediate applications of this method.
