Title (EN) METHOD FOR MEASURING A CONCENTRATION OF A GAS
(FR) PROCÉDÉ ET APPAREIL DE MESURE D'UNE CONCENTRATION D'UN GAZ
Abstract:
(EN) A method of measuring a concentration of a gas in the headspace of a container is provided. The headspace contains particles and/or droplets and/or the container carries on an exterior section surrounding the headspace particles and/or droplets. The container is at least in parts transparent to electromagnetic radiation. The method comprises the steps: - subjecting said headspace to input electromagnetic radiation; - receiving from said headspace output electromagnetic radiation in form of transmitted and/or reflected and/or diffused input electromagnetic radiation; and - generating from said received electromagnetic radiation a concentration indicative result; - thereby a) diffusing outside the container and distant from the container said input electromagnetic radiation and/or b) diffusing outside the container and distant from the container said output electromagnetic radiation and/or c) moving said headspace with respect to said input electromagnetic radiation. Furthermore, a method of producing a gas concentration tested container, an apparatus for performing the methods and an automatic headspace gas analyzer are provided.
(FR) L'invention concerne un procédé de mesure d'une concentration d'un gaz dans l'espace libre d'un récipient. L'espace libre contient des particules et/ou des gouttelettes et/ou le récipient porte sur une section extérieure entourant les particules et/ou gouttelettes d'espace libre. Le récipient est au moins en partie transparent au rayonnement électromagnétique. Le procédé comprend les étapes consistant à : - soumettre ledit espace libre à un rayonnement électromagnétique d'entrée; - recevoir à partir dudit espace libre un rayonnement électromagnétique de sortie sous la forme d'un rayonnement électromagnétique d'entrée émis et/ou réfléchi et/ou diffusé; et - générer à partir dudit rayonnement électromagnétique reçu un résultat indicatif de concentration; - ainsi a) diffuser à l'extérieur et à distance du récipient ledit rayonnement électromagnétique d'entrée et/ou b) diffuser à l'extérieur et à distance du récipient ledit rayonnement électromagnétique de sortie et/ou c) déplacer ledit espace libre par rapport audit rayonnement électromagnétique d'entrée. En outre, l'invention concerne un procédé de production d'un récipient testé à la concentration de gaz, un appareil pour mettre en œuvre les procédés et un analyseur de gaz d'espace libre automatique.
