| Research Abstract |
Volatile organic compounds (VOCs) in exhaled breath reflect products of metabolism in our body in the expired air. Therefore, noninvasive breath analysis has the potential of replacing blood and urine analyses for many compounds. Monitoring breath acetone and/or isoprene can be useful to follow patients on a prescribed diet regimen. In this work, a flow injection analysis (FIA) system was developed for the determination of breath acetone. The FIA system has been successfully applied to the monitoring of variation of breath acetone affected by meal and exercise. A new FIA system was also proposed for the determination of gaseous isoprene.
