  • Title: Porous-layer open-tubular gas chromatography in combination with an ion trap detector to assess volatile metabolites in human breath.
    Author: Ghoos Y, Hiele M, Rutgeerts P, Vantrappen G.
    Journal: Biomed Environ Mass Spectrom; 1989 Aug; 18(8):613-6. PubMed ID: 2804446.
    Abstract:
    A method is described for the quantification of major volatile substances in human breath without preconcentration. Methanol, ethanol, acetaldehyde and acetone are well separated by porous-layer open-tubular column gas chromatography. Low-level detection was possible by means of an ion trap detector. Halothane has been used as internal standard.
