Document Type and Number:
Japanese Patent JP2002536673
Kind Code:
A
Abstract:
A modular flow cell 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 having two ends, each with a respective end interface secured thereto. The flow cell is configured to form a part of a modular flow cell assembly. The flow cell body includes a channel having a through-aperture with an inner surface. A light guiding material, 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. The channel 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.
