Human biomarkers in breath by photoacoustic spectroscopy

Clin Chim Acta. 2012 Aug 16;413(15-16):1171-8. doi: 10.1016/j.cca.2012.04.008. Epub 2012 Apr 16.

Abstract

Photoacoustic spectrometry provides a novel approach to the analysis of human breath biomarkers. This unique methodology has specific applications for determination of ethylene oxide, nitrous oxide, ammonia as well as other compounds of interest including sevoflurane, halothane, isoflurane, methane, ethane and propofol. The advantages and disadvantages of photoacoustic spectrometry for this purpose are evaluated.
