<p>A total amount of volatile organic compounds (VOCs) in a breath sample (101) is detected by oxidizing/burning (120) the VOCs to form CO<SUB>2</SUB> and H<SUB>2</SUB>O, and the amounts of one or both of these compounds are measured (130). CO<SUB>2</SUB> and H<SUB>2</SUB>O molecules in the breath sample (101) are removed (110) before the VOCs are converted (120) to CO<SUB>2</SUB> and H<SUB>2</SUB>O. Because one VOC molecule contains multiple carbon and hydrogen atoms, the number of formed CO<SUB>2</SUB> and H<SUB>2</SUB>O molecules will be substantially larger than the original number of VOC molecules, thereby improving the sensitivity of the detection.</p> |
