Abstract
A chromatographic flow cell having the capacity to handle fluid flow from one or more chromatographic systems, at widely varying flow rates without the need to change flow cells or detectors. The flow cell itself acts as a tee where two or more fluidic inlet lines intersect with a common inlet channel. The common inlet channel is configured so that the diameter and length minimizes the total volume, unswept volume, bandspreading, and backpressure. The common outlet channel, inlet lines and the outlet line are sized to provide for adequate fluidic handling at the varied flow rates.
