Nitschke et al (1998) analysed indoor nitrogen dioxide levels by selecting a cohort of 129 asthmatics and ensuring they wore diffusion badge monitors while indoor gas appliances are being used, which is seen as potentially the greatest period of exposure. Levels were expressed at time-average nitrogen dioxide concentration, because daily badge exposure times differed (mean 4.5 hours, sd 2.4). 4, record 1, English, - passive%20diffusion%20badge

«vanne d'introduction» : Dispositif permettant d'introduire de façon reproductible un volume de gaz à analyser dans le circuit d'analyse. Le plus souvent une vanne d'introduction comprend deux circuits gazeux distincts et un volume appelé "boucle d'échantillonnage" qui fait partie de l'un ou l'autre circuit, selon que la partie mobile de la vanne est dans l'une ou l'autre position : elle peut généralement être considérée comme constituant le point d'échantillonnage d'une installation d'analyse.

On préfère utiliser une boucle d'échantillonnage [...] dont le tube en U [...] constitue l'élément essentiel. Le gaz à analyser traverse ce tube [...]. Les vannes à gaz [...], qui peuvent être rotatives ou à piston, fonctionnent sur le même principe; disposées à la place de la chambre d'introduction, elles évitent la dilution de l'échantillon dans le volume de cette chambre qui précède la colonne. 2, record 3, French, - vanne%20%C3%A0%20gaz
