Title (EN) FITTING ASSEMBLY FOR ANALTICAL APPLICATIONS
(FR) ENSEMBLE FIXATION POUR DES APPLICATIONS ANALYTIQUES
Abstract:
(EN) An improved fitting assembly for analytical devices is provided. The fitting assembly includes a tube securable to a fitting component via rear and front ferrules and a nut. The fitting component includes a body having a cavity for receiving the tube and ferrules. The body also includes a channel connecting the cavity to a leak chamber defined in a space between the tube, the fitting component and the inner sidewall of the nut body, the leak chamber being in fluid communication with the exterior of the nut body via the channel in the nut body. Sealing elements are provided between the tube and nut for encouraging leaks to flow through the leak path. A method for detecting leaks in the fitting assembly is also provided.
(FR) L'invention concerne un ensemble fixation amélioré pour des dispositifs d'analyse. L'ensemble fixation comprend un tube pouvant être fixé à un élément de fixation par l'intermédiaire de viroles avant et arrière et d'un écrou. L'élément de fixation comprend un corps ayant une cavité pour accueillir le tube et des viroles. Le corps comprend également un canal reliant la cavité à une chambre de fuite délimitée dans un espace compris entre le tube, l'élément de fixation et la paroi latérale interne du corps d'écrou, la chambre de fuite étant en communication fluidique avec l'extérieur du corps d'écrou par l'intermédiaire du canal dans le corps d'écrou. Des éléments d'étanchéité sont disposés entre le tube et l'écrou pour encourager les fuites à s'écouler par le chemin de fuite. L'invention concerne également un procédé pour détecter des fuites dans l'ensemble fixation.
