Product Description This Waters 474 scanning fluorescence detector has advanced programming and scanning capabilities. The Waters 474 Scanning Fluorescence Detector is a high-performance unit that provides a high level of sensitivity for spectrofluorometric analysis. Features include:

- Optical design that maximizes sensitivity
- Microprocessor control for greater versatility and reliability
- An emission wavelength sweep function so you can obtain an emission spectrum
- An excitation wavelength sweep function so you can obtain an excitation spectrum
- An automatic second-order filter to enhance applications in the visible wavelength
range
- Optional optical filters that can be installed on the flow cell for specialized
measurements (not included)
- can be used with quartz flow cell or cuvette cell, permitting measurement of ultraviolet fluorescence
- Nine-stage photomultiplier tube for amplifying the emission radiation
- Photodetector to compensate for excitation fluctuations throughout a scan
There are three critical optical design features in the 474 detector:
- A highly energy-efficient optics system that does not use lenses, minimizing
reflection loss
- An optics system that uses holographic concave diffraction gratings and aspherical
mirrors to provide highly efficient monochromators in a compact package
- A 150 W Xenon lamp that provides greater light energy for excitation
There are five critical microprocessor-based features:
- Operating parameters that are set using the keypad
- A multi-line liquid crystal display (LCD) that provides information on the status of the
474 detector
- Self-diagnostic messages that are displayed on the LCD
- Digital processing that controls the entire signal processing system, assuring higher
reliability and operational stability
- An auto-zero feature that provides a wide range of offset adjustment for the analog
output
