Possibilities of measuring the exhaled air composition using Raman spectroscopy

A Raman spectrometer for gaseous media with a detection limit at a level of 100 ppb is developed. The results of its experimental approval on exhaled air samples from healthy people confirmed the possibility of monitoring the concentrations of a number of hydrocarbon compounds and (CO2)-C-13. The ways of further development of this analytical method are outlined.
