Abstract

In this study, a photoacoustic detector integrated with Fourier-transform infrared spectroscopy was used to measure biomarkers in gas samples independently. Simulated exhaled breath samples were created by mixing varying concentrations of acetone, ammonia and ethane. The results of these measurements demonstrate the potential of photoacoustic spectroscopy to detect biomarkers from human breath.
