The PolySense and Polysense Innovations teams have just published  a new article on ACS Sensors Journal (IF 9.1)  reporting on the development of a dual-gas Quartz-Enhanced Photoacoustic Spectroscopy (QEPAS) sensor operating in the mid-infrared range for the simultaneous detection of 12CH4 and 13CH4. The sensor employs a frequency-modulated multiplexing scheme using two distributed-feedback quantum cascade lasers to Leggi di piùNew Publication on ACS Sensors journal[…]
