This is a used Waters 2475 Multi-Wavelength Fluorescence Detector
The 2475 Multi-Wavelength Fluorescence Detector is a multi-channel, tunable, fluorescence detector designed for HPLC applications. The detector delivers the highest sensitivity and selectivity, whether you are monitoring low concentrations of target compounds or low-level impurities. Use the detector as a stand-alone unit or as an integral part of a Waters chromatography system. It operates from 200 to 900 nm and uses newly designed optics, with an enhanced illumination system, for improved performance. These design features increase the optical thrughput and sensitivity resulting in an overall increase in the signal-to-noise ratio.
Features:
- Innovative axially illuminated flow cell designed for less dispersion, less stray light, less volume, and more pathlength for maximum sensitivity
- Three-dimensional spectral scanning for faster method development and optimization, and enhanced peak identification
- Single or multi-channel operation monitors fluorescence at one or more discrete wavelength pairs
- Low noise performance – Less stray light due to orthogonal optics and the use of mirrors, not lenses, minimize scatter
- Multiple detection modes – 2D, 3D, and on-the-fly spectral scanning – can greatly reduce the time needed to develop fluorescence detection methods by quickly determining wavelength maxima
- Integral erbium calibration reference – ensures wavelength accuracy
- Normalized emission units for better bench-to-bench reproducibility
