The Waters 474 Scanning Fluorescence Detector
Includes:
An 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
Quartz flow cell or cuvette cell, permitting measurement of ultraviolet fluorescence
Nine-stage photomultiplier Aube for amplifying the emission radiation
Photodetector to compensate for excitation fluctuations throughout a scan
An RS-232 port to allow connectivity to the Millennium32 data system
There are three main 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 main 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
