Abstract:	Quartz-enhanced photoacoustic spectroscopy (QEPAS) employs a quartz tuning fork (QTF) as detector for the photoacoustic signal and enables laser spectroscopic gas sensors with extraordinarily high detection sensitivity [1]. We adapted this powerful technique for the analysis of solid and liquid samples and present potential applications and newest results. [1] B. Li, G. Menduni, M. Giglio, P. Patimisco, A. Sampaolo, A.
