Zusammenfassung:A first multi-channel optical flow cell (10, 100, 200, 540) includes a two end blocks (14, 114, 214, 16, 116, 216) disposed around a channel-defining flow layer (12, 112, 212, 292, 400, 410, 420, 430, 440, 450, 1212, 2212), with a first end block (14, 114, 214) having multiple inlet ports (20A-20X, 120X, 220A-220X) each containing an associated optical fiber (26A-26X, 126X, 535A-535X) and fluid conduit (24A-24X, 124X, 528A-528X) terminated substantially flush against an inner surface (40, 140) of the first end block (14, 114, 214). The second end block (16, 116, 216) may have multiple outlet ports (22A-22X, 122X, 222A-222X) each containing at least one of an additional optical fiber (30A-30X, 130X, 537A-537X) and additional fluid conduit (28A-28X, 128X, 529A-529X). A method for fabricating a multi-channel flow cell (10, 100, 200, 540) includes inserting a first plurality of optical fibers (26A-26X, 126X, 535A-535X) and a first plurality of fluid conduits (24A-24X, 124X, 528A-528X) through a plurality of inlet ports (20A-20X, 120X, 220A-220X) defined in a first end block (14, 114, 214), sealing the optical fibers (26A-26X, 126X, 535A-535X) and conduits (24A-24X, 124X, 528A-528X), polishing the optical fibers (26A-26X, 126X, 535A-535X), and then positioning and joining a channel-defining flow layer (12, 112, 212, 292, 400, 410, 420, 430, 440, 450, 1212, 2212) between the first end block (14, 114, 214) and a second end block (16, 116, 216). L'invention concerne une première cuve à circulation optique à canaux multiples (10, 100, 200, 540) comprenant des blocs terminaux (14, 114, 214, 16, 116, 216) disposés autour d'une couche d'écoulement définissant des canaux (12, 112, 212, 292, 400, 410, 420, 430, 440, 450, 1212, 2212), avec un premier bloc terminal (14, 114, 214) comprenant plusieurs orifices d'admission (20A-20X, 120X, 220A-220X) renfermant individuellement une fibre optique associée (26A-26X, 126X, 535A-535X) et un conduit de fluide (24A-24X, 124X, 528A-528X) à terminaison sensiblement encastrée contre une surface interne (40, 140) du premier bloc terminal (14, 114, 214). Le second bloc terminal (16, 116, 216) peut comprendre plusieurs orifices d'évacuation (22A-22X, 122X, 222A-222X) renfermant individuellement au moins une fibre optique supplémentaire (30A-30X, 130X, 537A-537X) et un conduit de fluide supplémentaire (28A-28X, 128X, 529A-529X). L'invention concerne également un procédé de fabrication d'une cuve à circulation à canaux multiples (10, 100,
