    • The present invention provides a detection cell that comprises a body having a first end that defines a first opening, a second end that defines a second opening, and an internal surface that defines an interior cavity that fluidly connects the first opening and the second opening; wherein the interior cavity is capable of holding a support matrix for receiving a chemical species through the first opening, passing the chemical species through the interior cavity, and discharging the chemical species through the second opening; and wherein at least two portions of the body are capable of providing a first and a second guiding region each having an index of refraction less than that of the support matrix. A system utilizing the detection cell of the present invention is also provided. In another embodiment, the present invention provides a method for guiding light through a support matrix through which a chemical species is passing.
    • 本发明提供了一种检测单元,其包括具有限定第一开口的第一端,限定第二开口的第二端和限定使第一开口和第二开口流体连接的内部空腔的内表面的主体; 其中所述内部空腔能够保持用于通过所述第一开口接收化学物质的支撑矩阵,使所述化学物质通过所述内部空腔,并且通过所述第二开口排出所述化学物质; 并且其中所述主体的至少两个部分能够提供每个具有小于所述支撑矩阵的折射率的折射率的第一和第二引导区域。 还提供了利用本发明的检测单元的系统。 在另一个实施方案中,本发明提供一种用于引导光通过化学物质通过的载体基质的方法。
