Quartz-enhanced photoacoustic NH(3) sensor exploiting a large-prong-spacing quartz tuning fork and an optical fiber amplifier for biomedical applications

A sensor system for exhaled ammonia (NH(3)) monitoring exploiting quartz-enhanced photoacoustic spectroscopy (QEPAS) was demonstrated. An erbium-doped fiber amplifier (EDFA) with an operating frequency band targeting an NH(3) absorption line falling at 1531.68 nm and capable to emit up to 3 W of opt...
