There's been some interest in using spectroscopic techniques to analyse breath. Molecules found in breath are markers for disease. The high stability and portability of your equipment is well suited to this field.
Ammonia is a sign of liver and kidney problems as described in Breath Ammonia Analysis: Clinical Application and Measurement by Hibbard and Killard.
Various markers are known for lung diseases as detailed in Biomarkers of some pulmonary diseases in exhaled breath by Sergei A. Kharitonov and Peter Barnes
The question that remains is that of sensitivity. Does MicroFTS have what it takes?
