The new approach, termed coherently controlled quartz-enhanced photoacoustic spectroscopy (QEPAS), could form the basis for detectors used in environmental monitoring, breath analysis and chemical ...

To achieve fast detection of low gas concentrations, the researchers combined a laser with an extremely fast tunable wavelength with quartz-enhanced photoacoustic spectroscopy and integrated ...

and remote detection of explosive gas leakage in extremely narrow spaces. More information: Jun Ma et al, Microscale fiber photoacoustic spectroscopy for in situ and real-time trace gas sensing ...

They also leveraged quartz-enhanced photoacoustic spectroscopy (QEPAS) as the sensitive detection mechanism. This spectroscopy approach uses a quartz tuning fork to detect gas absorption by ...

The miniaturized all-fiber photoacoustic spectrometer (FPAS ... The fiber's end facet and the membrane form a Fabry-Perot cavity. When gas molecules absorb pump light, they generate acoustic ...
