## Abstract Amino acid (AA) enantiomers were determined as __N(O)__โpentafluoropropionylโ(2)โpropyl esters by chiral gas chromatographyโmass spectrometry (GCโMS) in 24โ h samples of the urine of three healthy volunteers and in their blood sera. In urine the largest amounts were determined for DโSer
We present gas chromatographic/mass spectrometric and gas chromatographic/isotope ratio mass spectrometric assays of the 13C enrichment of plasma urea converted to its dimethylaminomethylene derivative. The limits of sensitivity of the two techniques are 0.2% and 0.02%, respectively. The techniques
