Title
(EN) NMR MEASUREMENT UNIT FIXABLE WITHIN A PROCESS CHANNEL
(FR) UNITÉ DE MESURE DE RM POUVANT ÊTRE FIXÉE À L'INTÉRIEUR D'UN CANAL DE TRAITEMENT
Abstract
(EN)
The invention relates to an NMR measurement unit (10), which includes - a flow channel (12) for separating a sample from a fluid stream in a process channel (18), - a magnet (20) arranged in relation to the flow channel (12) for creating a magnetic field (E) at least in part of the flow channel (12), - a coil (22) arranged in relation to the flow channel (12) for exciting NMR active nuclei of the sample moving in the flow channel (12) and for receiving the frequency pulse that returns to the coil (22) from the NRM active nuclei, - a frame (24) comprising a fastening flange (26) for sealing the NMR measurement unit (10) to the process channel (18) and a chamber (28) that is closed at least relative to the fluid stream and connected to the fastening flange (26), arranged to be installed at least mainly inside the process channel (18), within which chamber (28) the magnet (20) and coil (22) are arranged and through which chamber (28) the flow channel (12) passes, the frame (24) being installable in such a way that the flow channel (12) is positioned inside the process channel (18). The invention also relates to an NMR measurement system (100).

L'invention concerne une unité de mesure de RMN (10), qui comprend - un canal d'écoulement (12) pour séparer un échantillon d'un courant de fluide dans un canal de traitement (18), - un aimant (20) disposé par rapport au canal d'écoulement (12) pour créer un champ magnétique (E) au moins dans une partie du canal d'écoulement (12), - une bobine (22) disposée par rapport au canal d'écoulement (12) pour exciter des noyaux actifs de RMN de l'échantillon se déplaçant dans le canal d'écoulement (12) et pour recevoir l'impulsion de fréquence qui revient à la bobine (22) en provenance des noyaux actifs de RMN, - un cadre (24) comprenant une bride de fixation (26) pour sceller l'unité de mesure de RMN (10) au canal de traitement (18) et une chambre (28) qui est fermée au moins par rapport au courant de fluide et reliée à la bride de fixation (26), conçue pour être installée au moins principalement à l'intérieur du canal de traitement (18), chambre (28) à l'intérieur de laquelle sont disposés l'aimant (20) et la bobine (22) et chambre (28) à travers laquelle passe le canal d'écoulement (12), le cadre (24) pouvant être installé de telle sorte que le canal d'écoulement (12) soit positionné à l'intérieur du canal de traitement (18). L'invention concerne également un système de mesure de RMN (100).
