New Publication on Applied Science

The PolySense team has just published  a new article on Applied Science reporting  on a study of the front-end electronics for quartz tuning forks (QTFs) employed as optoacoustic transducers in quartz-enhanced photoacoustic spectroscopy (QEPAS) sensing. We demonstrated that the fully di erential voltage amplifier allows for a nearly doubled SNR with respect to the typically used single-ended Leggi di piùNew Publication on Applied Science[…]

The PolySense team has just published  a new article on Applied Science reporting on the realization of a quartz-enhanced photoacoustic spectroscopy (QEPAS)-based ethane gas sensor operating in the near-IR  and  employing a pigtailed laser diode emitting at ~1684 nm as the exciting light source.  The minimum ethane concentration detectable using a 100 ms lock-in integration time achieving Leggi di piùNew Publication on Applied Science[…]
