Claims6
Arrangement for collection of volatile organic components in alveolar breath comprising:
- a hollow container having a first end and a second end, a breath entry portal proximal to said first end, a breath exit portal proximal to said second end, and a sampling portal between said entry and said exit portals;
- a condensation unit downstream from said sampling portal relative to said hollow container, and
- a sorbent trap downstream from said condensation unit.
A method for analyzing volatile organic components in alveolar breath comprising:
- receiving a breath sample in a breath reservoir,
- withdrawing alveolar breath from said breath sample,
- conveying said alveolar breath to a condenser,
- removing water vapor present in said alveolar breath in said condenser,
- thereafter contacting said alveolar breath with a sorbent trap, and
- analyzing volatile organic components absorbed into said sorbent trap from said alveolar breath.
