Abstract

L'invention permet de détecter et de quantifier les densités de vapeur d'eau dans un gaz à une fréquence d'échantillonnage élevée. Le gaz peut être contenu dans une chambre d'échantillonnage à l'intérieur ou à l'extérieur de l'enceinte d'un instrument. Un premier faisceau divisé traverse l'enceinte et la chambre d'échantillonnage alors qu'un deuxième faisceau divisé traversant uniquement l'enceinte constitue une référence susceptible d'être utilisée pour corriger l'humidité ambiante dans l'enceinte de l'instrument.
