    Abstract: A photocatalysis testing device includes a reaction chamber, a light source, and a spectrophotometer. Reactants including a methylene blue (MB) solution and a photocatalyst can be added to the reaction chamber and illuminated by the light source. Color vanishing rate of the MB solution can be measured by the spectrophotometer. Further, the photocatalysis testing device also includes a light-tight chamber and a temperature stabilizer. The reaction chamber and the light source are received in the light-tight chamber to avoid ambient light effecting on the photocatalysis test. The spectrophotometer is positioned outside the light-tight chamber and optically coupled to the reaction chamber. The temperature stabilizer is configured for stabilizing temperature of the MB solution.

    Abstract: Fiber optic sensors employ a high brightness light source such as a fiber optic supercontinuum source, multiplexed superluminescent light emitting diodes, or a broadband tunable laser diode. Light is delivered to the measurement location via fiber optics and sensor optics directs infrared radiation onto material the being monitored that is located in a hostile environment. A disperse element is positioned in the detection beam path in order to separate the wavelengths and to perform spectral analysis. A spectral analysis of the radiation that emerges from the sheet yields information on a plurality of parameters for the material. For papermaking applications, the moisture level, temperature and cellulose content in the paper can be obtained.
