A coated flow cell and a method for making the coated flow cell are provided. The flow cell comprises a flow passage internally coated with a polymer having an index of refraction lower than that of water. In this manner, light directed into the flow cell is internally reflected or “piped”down the length of the flow passage. As a result, flow cells having path lengths significantly longer and accepting incident angles of light much greater than possible with prior art flow cells. A method for internally coating the flow cell is also provided.
