<p>A modular flow cell (10) having a high optical throughput, a long optical path length and a small cross-section. The modular flow cell configuration includes remote ports or connections for liquid and light input, and liquid and light output. The flow cell includes a flow cell body (20) having two ends, each with a respective end interface secured thereto. The flow cell (10) is configured to form a part of a modular flow cell assembly. The flow cell body (20) includes a channel (32) having a through-aperture with an inner surface (26). A light guiding material (28), e.g. a transparent fluoropolymer material having a refractive index less than the refractive index of common chromatography solvents, is disposed proximate to the channel to form a light guiding through-aperture in the flow cell body (20). The channel (32) is formed of materials that can provide the necessary mechanical strength and a fluid seal, and more particularly, includes materials such as polyetheretherketone (PEEK), which can develop a fluid seal at the interface between the flow cell body end and each end interface.</p> |
