[Article in German]


The acidic compounds of urine were separated by thin-layer chromatography in eight fractions. Each fraction was investigated separately by the combination glass capillary gas chromatography-mass spectrometry. About 500 compounds were detected, 2/5 of these could be characterized by their mass spectra. Retention data and key fragments of the mass spectra were tabulated. Many of the detected compounds are still unknown.
