Ammonia in breath is a biomarker that reflects the state of liver and kidney function.
In this report, we used a measurement system consisting of a distributed feedback quantum cascade laser (DFB-QCL) and a hollow optical fiber gas cell to detect trace amounts of ammonia gas in breath using mid-infrared spectroscopy. We report on the results of an attempt to accurately quantify the ammonia concentration in breath by releasing and collecting ammonia adsorbed to soda lime used in the dehydration process.
