RF 2000 fluorescence detector

RF 2000 fluorescence detector: performance and reliability for your chromatographic analyses

The RF 2000 fluorescence detector from Thermo Fisher Scientific is a benchmark instrument for laboratories using Summit™ HPLC and DX-500/DX-600 IC systems. Designed to meet the most demanding analytical requirements, it incorporates two independent monochromators, ensuring precise reproducibility of excitation and emission wavelengths. This design ensures that methods can be finely tuned to the optimal detection conditions for each component.

Thanks to its optimised optical and electronic system, the RF 2000 achieves remarkable sensitivity. It offers a signal-to-noise ratio greater than 300:1 over the Raman spectrum of water, facilitating the detection of trace components. Excellent wavelength accuracy, with a repeatability of ± 0.2 nm, guarantees reliable results and comparability between samples.

The RF 2000 also allows time programming of the excitation and emission wavelengths, optimising the specific response of each compound analysed. It offers the possibility of recording spectra in a few seconds thanks to the wavelength scanning function, facilitating the identification of substances by comparison with libraries of known standards.

When connected to CHROMELEON™ software, the RF 2000 benefits from automated control of all its parameters. This increases laboratory productivity while ensuring complete traceability of operations in accordance with good laboratory practice (GLP).

In terms of applications, the RF 2000 is particularly used for the analysis of polycyclic aromatic hydrocarbons (PAHs) in drinking water, wastewater and surface water, in accordance with regulatory requirements. It is also suitable for toxicological, environmental and food analyses, such as the detection of aflatoxins, carbamates, vitamins and amino acids.

With its rigorous design and compatibility with automation tools, the RF 2000 detector is a reliable choice for laboratories seeking precision, sensitivity and reproducibility in their fluorescence analyses.
