The PolySense team has just published a new article on Photoacoustics Journal Elsevier (IF 5.87) demonstrating that quartz-enhanced photoacoustic spectroscopy (QEPAS) is an efficient tool to measure the vibrational relaxation rate of gas species, employing quartz tuning forks (QTFs) as sound detectors.
The following link provide access to the article.
