Abstract
An on-line fluorescence detection device comprises a reflective cavity, a material pool, a light source transmitting device and a fluorescence receiving device, wherein the reflective cavity is elliptical, and a reflective face is arranged on the inner wall of the reflective cavity; the material pool is used for bearing materials to be detected and made of a transparent material; the material pool is located on one focus of an ellipse in the reflective cavity; the light source transmitting device is used for transmitting exciting light to the material pool; the fluorescence receiving device is located on the other focus of the ellipse in the reflective cavity. As the material pool is located on one focus in the elliptical reflective cavity, and the fluorescence receiving device is located on the other focus in the elliptical reflective cavity, fluorescence emitted in the material pool is reflected onto the fluorescence receiving device by the elliptical reflective cavity, and accordingly, the fluorescence receiving efficiency is improved; the on-line fluorescence detection device is simple in structure, low in cost and convenient to use.
