	Outstanding sensitivity with an S/N ratio at 900 or higher for Raman spectra of water Model L-2485 Fluorescence Detector is an optical system with a reduced loss of light achieved by the integration of Hitachi's advanced technologies, such as 3-D optical axial arrangement design, innovative converging mirror, slit flow cell, and optimized monitoring system of transmitted light. The improved flow cell has been newly added to achieve a signal-to-noise ratio at 900 or higher for Raman spectra of water (with the baseline method). Use of a switchable slit The fluorescence spectroscopic slit of the L-2485 can be switched between 15 nm and 30 nm. Use the 30-nm slit for high-sensitivity data analysis. Automatic wavelength check The emission beam of a built-in Hg lamp is used to perform an automatic check of wavelengths at 254 nm, which is most frequently used for HPLC analysis. Easy front-access maintenance Maintenance is easy. You can load the flow cell and adjust the position of the Xe lamp all from the front side of the instrument.
