Abstract

A first multi-channel optical flow cell includes a two end blocks disposed around a channel-defining flow layer, with a first end block having multiple inlet ports each containing an associated optical fiber and fluid conduit terminated substantially flush against an inner surface of the first end block. The second end block may have multiple outlet ports each containing at least one of an additional optical fiber and additional fluid conduit. A method for fabricating a multi-channel flow cell includes inserting a first plurality of optical fibers and a first plurality of fluid conduits through a plurality of inlet ports defined in a first end block, sealing the optical fibers and conduits, polishing the optical fibers, and then positioning and joining a channel-defining flow layer between the first end block and a second end block.
