Ppb-level NH3 photoacoustic sensor combining a hammer-shaped tuning fork and a 9.55µm quantum cascade laser
We present a quartz enhanced photoacoustic spectroscopy (QEPAS) gas sensor designed for precise monitoring of ammonia (NH3) at ppb-level concentrations. The sensor is based on a novel custom quartz tuning fork (QTF) with a mid-infrared quantum cascade laser emitting at 9.55 µm. The custom QTF with a...
