2 General Information
2.1 Outline
The basic design concept of the Dionex Fluorescence Detector RF-2000 is to
enhance productivity of analysis through its highest performance and stability.
This concept is realized by the highest sensitivity of the detector (higher than 300
signal to noise ratio for Raman spectrum of water), the highest wavelength accuracy
(± 2nm), the highest wavelength reproducibility (± 0.2nm) and the GLP/GMP
compliance support and improvement of operational safety.
The Dionex RF-2000 supports operation via the data system CHROMELEON.
Please refer to the sections "7.2 Control from External Equipment via RS-232C" and
"7.2.3 Controlling the RF-2000 via CHROMELEON" for details.
2.2 Features
• Greater sensitivity
The reengineered RF-2000 optical system provides significantly increased
sensitivity (signal-to-noise ratio greater than 300 for Raman spectrum of water).
Furthermore, use of appropriate excitation and emission spectral scan conditions
together with wavelength time programming allow high sensitivity detection of
multiple components at trace level concentrations.
• Enhanced wavelength accuracy
The RF-2000 offers unsurpassed wavelength accuracy (± 2nm) and wavelength
reproducibility to further enhance the reliability of wavelength selectivity and unit-
to-unit performance.
• Support for GLP/GMP compliance
Daily checks and log-keeping can be automated*. The standard validation
documents such as Certificate of Compliance and Hardware Validation SOP are
provided to facilitate compliance with regulatory requirements.
*With optional System Check software
• Enhanced safety features
Both heat and leak sensors are provided as a standard feature. In addition, the
lamp may be turned ON/OFF via time program, minimizing unnecessary lamp
consumption during continuous, unattended runs.
