Abstract
A novel method for the quantitative gas chromatographic analysis of phenylalanine in serum is presented. The procedure is based on the conversion of phenylalanine to the volatile derivative 2-trifluoromethyl-4-benzyl-3-oxazolin-5-one. After deproteinizing and evaporation to dryness of the serum sample, the phenylalanine is derivatized in one step by the action of trifluoroacetic anhydride in a closed vial at 130–140° for 10 minutes. Phenylglycine is used as internal standard.
