Photoacoustic Gas Detection with LED QEPAS

Not Accessible

Your library or personal account may give you access

Abstract

Various configurations and applications have been investigated and realized since the pioneering introduction of quartz-enhanced photoacoustic spectroscopy (QEPAS) by Kosterev et al. in 2002 [1]. However, the required submillimeter diameter of the acoustic resonator demands an excellent beam quality of laser source and precise adjustments of the QEPAS system. In a new approach, the off-beam resonator scheme [2] is proposed for avoiding these demands of conventional QEPAS systems. The positioning of tuning fork within the beam path is no longer necessary (Fig. 1).
