Shimadzu's New RF-6000 Spectrofluorophotometer Combines Superior Analysis Capabilities with Enhanced Ease of Use

Shimadzu has released its new RF-6000 spectrofluorophotometer which provides stable analyses at a level of sensitivity that is unrivaled by other instruments in its class.

The RF-6000 offers the highest sensitivity and signal-to-noise ratio* (SNR) in its class (SNR ≥1,000 RMS and ≥350 peak-peak). This high sensitivity enables very low limits of quantitation, easily achieving quantitation of fluorescein to concentrations of 1 × 10^-13 mol/L. In addition, an auto-gain control function ensures that measurements are performed without an influence of environmental factors. As a result, the system can perform accurate and highly quantitative measurements over a wide six-order dynamic range, from 10^-13 to 10^-7 mol/L.

Furthermore, the lifespan of the xenon arc lamp has been extended greatly, to approximately 2,000 hours. This, combined with the wider range of the detector's measurable wavelengths, assures stable analyses with high precision. In addition, a larger sample compartment, the adoption of the new LabSolutions RF control software and a wealth of options mean that an even broader range of customer needs can be accommodated.

Features

1. Outstanding sensitivity, high-speed 3D measurement and long-lasting light source

By optimizing the internal design, the RF-6000 achieves an SNR* of 350:1, the highest in its class, allowing for high-sensitivity analyses of a wide range of samples. Moreover, the speed of 3D measurements has been increased significantly, enabling the acquisition of a 3D spectrum of the full wavelength range in a short time. Samples in very low concentrations or in minute amounts can also be analyzed by making use of optional cells designed for analyzing trace amounts. Lastly, the light source employs a highly stable xenon arc lamp. The illumination lifespan has been increased approximately four-fold to around 2,000 hours, helping to reduce running costs.

2. Measurements in the long wavelength range up to 900 nm possible as a standard feature; even more comprehensive range of applications now available

It is possible to obtain fluorescence spectra up to 900 nm with a standard configuration. In addition, the RF-6000 can be applied to new applications, for example measurement of quantum yield and quantum efficiency in order to evaluate the efficiency of a luminescent material, low-temperature measurement to enable recovery of a sample in order to elucidate artificial photosynthesis, or a search for methods to determine the place of origin for foodstuffs.

3. Enhancements in usability - new control software and a large sample compartment

By adopting the new LabSolutions RF control software, it is now easier to set up an integrated system of analyses and to evaluate the suitability of certain instruments. Since it is possible to constantly monitor areas such as illumination lamp lifespan, recognition status of options and the operational status of instruments, operators can enjoy a greater sense of confidence when using the equipment. Moreover, since the instrument is equipped as standard with functionality providing real-time acquisition of corrected spectra, even more accurate comparisons with spectra acquired by other analysis instruments can be performed. The RF-6000 also features a large sample compartment, enabling the use of a broader range of accessories.

* SNR: Signal-to-noise ratio. The higher the SNR, the more the effects of noise are reduced. This means that even the smallest peaks can be detected.
