The detection cell includes a substrate that defines a cavity. The cavity has a substantially planar floor and at least one wall with an opening there through. The detection cell also includes a prism disposed adjacent the opening. The prism is configured to redirect light through the opening into the cavity at an angle substantially parallel to the floor. Once a chemical sample is positioned in the cavity, light is directed at the prism. The prism is disposed adjacent an opening leading into a cavity containing a chemical sample. Subsequently the light is reflected within the prism to pass through the opening and into the cavity to illuminate the chemical sample.
