A detailed review on the development of quartz-enhanced photoacoustic sensors (QEPAS)
for the sensitive and selective quantification of molecular trace gas species with resolved …

As a new energy source, hydrogen (H2) detection is a hot topic in recent years. Because of
the weak absorption characteristic, laser spectroscopy-based H2 detection is challenging. In …

Abstract Fabry–Perot (F–P)-based phase demodulation of heterodyne light-induced
thermoelastic spectroscopy (H-LITES) was demonstrated for the first time in this study. The …

In this paper, a highly sensitive photoacoustic spectroscopy (PAS) sensor based on retro-
reflection-cavity-enhanced differential photoacoustic cell (DPAC) is demonstrated for the first …

In this paper, a differential quartz-enhanced photoacoustic spectroscopy (D-QEPAS) sensor
is reported. The differential photoacoustic cell (PAC) was used to generate the …

Methane (CH 4) is a greenhouse gas as well as being flammable and explosive. In this
manuscript, quartz-enhanced photoacoustic spectroscopy (QEPAS) and heterodyne QEPAS …

Due to its advantages of non-contact measurement and high sensitivity, light-induced
thermoelastic spectroscopy (LITES) is one of the most promising methods for corrosive gas …

In this Letter, two novel, to the best of our knowledge, quartz tuning forks (QTFs) with
trapezoidal-head and round-head were designed and adopted for quartz-enhanced …

In this paper, an ultra-highly sensitive light-induced thermoelastic spectroscopy (LITES)
based hydrogen chloride (HCl) sensor, exploiting a custom low-frequency quartz tuning fork …
