Abstract (en)
[origin: WO2010142908A1] The invention relates to a device for dynamically determining the concentration of a compound in a flowing aqueous phase. The invention also relates to a device (300) for determining the concentration of a compound in a gaseous phase that is soluble in an aqueous phase. The device (200, 300) for determining the concentration of a compound in a gaseous phase comprises means (302) for transferring the compounds present in the gaseous phase towards and aqueous phase and for dynamically determining during the circulation the concentration of the compounds in said aqueous phase by fluorescence spectroscopy. The devices (300) of the present invention are sturdy, portable, and have a lower cost and a higher time and space sensitivity than the devices of the prior art.
