System for measuring a color property of a liquid |
摘要 |
A system utilizing the flow cell of the present invention includes a reflectance mode spectrophotometer positioned with respect to the flow cell or a probe. Either the flow cell or the probe has a thin partition mounted in spaced relationship with respect to a transparent window. The partition has a predetermined index of refraction and has a thickness dimension that is less than that of the window. The spacing between the partition and the window is such that evanescent coupling of radiation reflected from the liquid into the material of the window is prevented. The spectrophotometer is directs interrogating radiation toward a liquid flowing through the sample chamber and responds to interrogating radiation reflected from the liquid to produce an electrical signal representative of a color property thereof.
