Trace composition of human respiratory gas

Arch Environ Health. 1975 Jun;30(6):290-5. doi: 10.1080/00039896.1975.10666702.

Abstract

A multistage cryogenic trapping system was used to sample and concentrate trace organic constituents in human respiratory gas. Chemical analysis was conducted by gas chromatography and mass spectrometry. Respiratory compound identification and production rate data are given for eight human test subjects. This study reports on the use of the sampling technique to diagnose metabolic diseases and for application in the study of industrial exposure.
