Abstract
Samples of human breath and head space vapors over saliva have been analyzed in a gas chromatograph equipped with a flame ionization detector. A simple direct sampling method without any enrichment procedure has been used. At the highest sensitivity of the chromatograph about 10 different peaks could be registered. Individual variations and the influence of food, alcohol and smoking have been demonstrated. The effect of a preparation for oral hygiene has also been shown. A typical chromatographic pattern for breath and saliva vapors has been constructed. The analytical technique presented could be applied to other problems in medicine and biochemistry.
