Specific detection of volatile metabolites in urines of normal subjects and patients with diabetes mellitus using computerized mass fragmentography.
Volatile urinary components are analyzed by a combination of gas chromatography, mass spectrometry and a data-acquisition system. Mass fragmentograms using the mass spectrometric data on magnetic tape are recorded for the primary aliphatic alcohols ethanol, n-propanol, isobutanol and isopentanol and the ketones 4-hepatonone and cyclohexanone. The mass fragmentograms are used as selective profiles to facilitate recognition of abnormalities in the urinary components in cases of diabetes mellitus.
