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.
A flow cell for light absorption measurement comprising: a housing comprising an outer layer of a heat shrinkable polymer and an inner layer of a second polymer, said inner layer of said second polymer forming an interior wall defining a flow passage, said flow passage having an inlet and an outlet through which a liquid phase sample to be analyzed is directed, said housing having a first end and a second end, said first and second ends having transparent windows through which light is directed, and at least a portion of said interior wall having bonded ...
