    SIFT-MS Analysis of Nose-Exhaled Breath; Mouth Contamination and the Influence of Exercise

  • Original language description

    The value of selected ion flow tube mass spectrometry, SIFT-MS, for the sampling and analysis of trace me- tabolites in both mouth-exhaled and nose-exhaled breath is discussed, and the latter is shown to circumvent oral contami- nation. Results of experiments are described in which increased levels of ammonia and ethanol deliberately generated in the oral cavity are clearly registered in mouth-exhaled breath but not in nose-exhaled breath. The value of the sampling methods that are used for the analysisof trace metabolites in both mouth-exhaled and nose-exhaled breath with selected ion flow tube mass spectrometry, SIFT-MS, is discussed, and their importance as a means to provide concentrations of truly endogenous compounds by circumventing their oralcontamination is demonstrated. Further to this, data are pre- sented on the direct analysis by SIFT-MS of several compounds in the nose-exhaled breath of eight healthy volunteers during exercise on a stationary bicycle.
