Fluorescence Detectors Merge Sensitivity with Efficiency

Shimadzu has introduced a new series of fluorescence detectors. The RF-20A and RF-20Axs cover the full range of applications from routine analysis to high-performance analysis particularly in food, pharmaceutical and environmental applications as well as for the determination of amino acids. The sensitive fluorescence detector high-end version RF-20Axs enables the detection of trace-level compounds. The detectors complete the prominence LC/UFLC families with ultra-high sensitivity and fast LC capabilities. The RF-20A and –Axs series are based on a newly developed optical system. They offer a dual-channel mode and a data acquisition speed of up to 100Hz, enabling ultra-fast analysis of just 10ms response and an ultra-high sensitivity. They serve applications requiring lowest possible detection limits.

The high-end RF-20Axs provides a cell temperature control with cooling function. It ensures a constant detector cell temperature leading to excellent reproducibility without any loss of sensitivity. Furthermore, the RF-20Axs supports automatic validation of the wavelength by a built-in Mercury lamp. This feature supports multiple components analysis.

The flow cell and the lamp are accessible from the front-side and provide easy maintenance, reducing running costs and downtime. No tools are required to replace the flow cell. In comparison to previous models, the life time of the Xenon lamp has been extended by a factor of 4 up to 2.000 hours. Due to a pre-adjusted lamp on a special holder it is unnecessary to adjust and tune the optical system after a lamp exchange.

Both detectors, the RF-20A and RF-20Axs offer an outstanding price-performance-ratio.
