Fluorescence Spectrophotometer Two modes could be chosen: fluorescence intensity and luminous intensity. Fluorescence scanning, kinetic determination, and quantity analysis could be done under the fluorescence intensity mode. 365nm exciting wavelength Raman peak of water in a 1 cm quartz fluorescence cuvette S/N=150  High performance sensitivity simplifies the measurement of low-detective samples. High stability and long life of 150W xenon lamp and power source ensure high stability testing and a wide range of spectrum.
