TL;DR: In this article, the authors explored the possibility of simultaneously determining both analytes by using more than one collector with dimensional differences and showed that differences in either length or wall thickness can permit such differentiation.

TL;DR: This work investigated the merits and pitfalls of isoprene measurement via its chemiluminescence (CL) reaction with ozone via its warm column preconcentration and passage through Ag+-form cation-exchange resin, which removes divalent sulfur gases.

TL;DR: An open tubular ion chromatograph that uses anion exchange latex coated 5 μm radius silica and poly(methyl methacrylate) tubes and automated time/pressure based hydrodynamic injection for pL-nL scale injections is described, discussed in the context of extraterrestrial exploration, especially Mars, where the existence of large amounts of perchlorate in the soil needs to be confirmed.

TL;DR: In this article, the authors describe a compact (5 cm diameter, 30 cm length) diffusion denuder with 11 individually wetted parallel screens, with an area in excess of 0.1 m2.

TL;DR: Comportement chromatographique de 30 anions sur phase stationnaire de poly(styrene-divinylbenzene) en utilisant des hydroxydes de tetraethyl and tetrapropylammonium comme reactifs d'interaction ionique as discussed by the authors.
