A review of methods for the preparation of standard gas mixtures (SGMs) with the known
concentrations of organic and inorganic gases and vapors is presented. The classification of …

We present the global research landscape which aims to deliver a measurement
infrastructure to underpin atmospheric observations of key greenhouse gases governing …

Cavity ring-down spectrometers have generally been designed to operate under conditions
in which the background gas has a constant composition. However, there are a number of …

Rationale Cavity ring‐down spectroscopy (CRDS) is becoming increasingly popular for
δ13C‐CO2 analysis of air. However, little is known about the effect of high 13C abundances …

Обзор различных методов приготовления стандартных газовых смесей (СГС) с
известной концентрацией органических и неорганических газов и паров. Предложена …

Abstract In 2009, the United States Congress charged the National Institute of Standards
and Technology (NIST) with supporting climate change research. As part of this effort, the …

We have developed a portable photoacoustic spectrometer that offers routine, precise and
accurate measurements of the molar concentration of atmospheric carbon. The temperature …

We present the global research landscape which aims to deliver a measurement
infrastructure to underpin atmospheric observations of key greenhouse gases governing …

This thesis describes an optical gas sensing system suitable for monitoring the presence of
carbon dioxide (CO2). An optical gas sensor using low cost and compact mid-infrared …
