| Outline of Final Research Achievements |
We have proved so far that flow injection analysis (FIA) and related techniques are useful for human breath analysis. In this project, a flow injection fluorometric determination of acetone in human breath was developed. Gaseous acetone in breath was sampled with a porous membrane based diffusion scrubber, then the absorbing solution including acetone merged with an alkaline salicylaldehyde, and the fluorescence intensity of salicylaldehyde decreased with increasing the acetone concentration. On the other hand, SIEMA systems we conceived can minimize the amount of sample solution and the reagent consumption. Also, it is a useful concept for automatic solution handling. We also proposed a SIEMA system for automatic pre-column derivatization HPLC determination of formaldehyde, acetaldehyde, acrolein and acetone. In the near future, an automated pre-column derivatization HPLC method for the determination of aldehydes and acetone in human breath using a SIEMA system would be developed.
