The PolySense team has just published  a new article on Applied Physics Letters reporting on an optical gas sensing technique based on in-plane quartz-enhanced photoacoustic spectroscopy (IP-QEPAS).  IP-QEPAS sensor results in a signal more than 40 times higher than that measured with the standard in-plane QEPAS configuration, confirming the potentiality of this approach.
