Optical gas sensing: a review
Jane Hodgkinson,Ralph P. Tatam +1 more
TL;DR: In this article, the authors present the basis for each technique, recent developments in methods and performance limitations, and present a performance comparison of different techniques, taking data reported over the preceding decade, and draw conclusions from this benchmarking.

4 Cavity ring-down and cavity enhanced spectroscopy using diode lasers
TL;DR: Continuous wave (cw) diode lasers are increasingly being used as light sources in the visible and near-IR regions of the spectrum for cavity ring-down spectroscopy (CRDS) and cavity enhanced absorption spectrograph (CEAS) as mentioned in this paper.
Journal ArticleDOI
Cavity-enhanced direct frequency comb spectroscopy: technology and applications.
TL;DR: Cavity-enhanced direct frequency comb spectroscopy combines broad bandwidth, high spectral resolution, and ultrahigh detection sensitivity in one experimental platform based on an optical frequency comb efficiently coupled to a high-finesse cavity.

On-line monitoring of volatile organic compounds at pptv levels by means of proton-transfer-reaction mass spectrometry (PTR-MS) medical applications, food control and environmental research
TL;DR: In this paper, a proton transfer reaction mass spectrometer (PTR-MS) was developed which allows for on-line measurements of trace components with concentrations as low as a few pptv.
Journal ArticleDOI
Cavity ring‐down optical spectrometer for absorption measurements using pulsed laser sources
TL;DR: In this paper, the authors have developed a technique which allows optical absorption measurements to be made using a pulsed light source and offers a sensitivity significantly greater than that attained using stabilized continuous light sources.
Journal ArticleDOI
Cavity ring-down spectroscopy: Experimental schemes and applications
TL;DR: Cavity ring-down (CRD) spectroscopy as mentioned in this paper is a direct absorption technique, which can be performed with pulsed or continuous light sources and has a significantly higher sensitivity than obtainable in conventional absorption Spectroscopy.
Journal ArticleDOI
A review of atmospheric aerosol measurements
TL;DR: A review of recent developments in atmospheric aerosol measurements can be found in this article, which focuses on measurements of aerosol integral properties (total number concentration, CCN concentration, optical coefficients, etc.), aerosol physical chemical properties (density, refractive index, equilibrium water content, etc.).
Journal ArticleDOI
The heterogeneous hydrolysis of NO2 in laboratory systems and in outdoor and indoor atmospheres: An integrated mechanism
TL;DR: In this article, the authors proposed a new reaction mechanism in which they hypothesize that the symmetric form of the NO2 dimer, N2O4, is taken up on the surface and isomerizes to the asymmetric form, ONONO2.
