Detection of methyl mercaptan (CH3SH) is essential for environmental atmosphere
assessment and exhaled-breath analysis. This paper presents a sensitive CH3SH sensor …

Attention has been focused recently on the harmful effects and malodor of methyl mercaptan
(CH 3 SH), so it is desired to detect CH 3 SH in situ, sensitively, and selectively. We detected …

This paper presents a mid-infrared dimethyl sulfide (CH3SCH3, DMS) sensor based on
tunable laser absorption spectroscopy with a distributed feedback interband cascade laser …

The ultrahigh-resolution mid-infrared absorption spectrum of methyl mercaptan (CH 3 SH)
was recorded and analyzed in the region of 2945–2953 cm-1, where the strong ν 2-band is …

We report the development of a compact near-infrared (NIR) laser-based trace methane (CH
4) detection system. This detection system relied on a 2334 nm distributed feedback (DFB) …

Abstract Methane (CH 4) and acetylene (C 2 H 2) are important bioscience and chemical
gases. The real-time monitoring and analysis of them have important research value in …

An efficient method for the detection of acetone, an important biomarker in exhaled breath,
by utilizing wavelength modulation spectroscopy (WMS) with a mid-infrared distributed …

An ultra-high sensitivity sensor combining a mid-IR (MIR) interband cascade laser (ICL) at
center wavelength of 3.37 μm and a multi-pass cell (MPC) with a path-length of 580 m was …

For sensitive and accurate methane (CH 4) and ethane (C 2 H 6) simultaneous detection, a
near-infrared dual-gas sensing system based on wavelength modulation spectroscopy …

A near-infrared (NIR) laser-based optical sensor was developed for atmospheric methane
(CH 4) measurement. The sensor adopted a distributed feedback (DFB) fiber laser operating …
