Shimadzu's new RF-20A and RF-20Axs fluorescence detectors provide sensitivity and validation support functions in a range of applications, from conventional to ultra-fast LC analysis.
Utilising a newly designed optical system, the RF-20A and the RF-20Axs have achieved high sensitivity levels, according to the company.
A water Raman S/N ratio of at least 1,200 for the RF-20A and 2,000 for the RF-20Axs makes these detectors suitable for tests requiring the analysis of trace-level components while retaining the acquisition speeds necessary for ultra-fast analysis.
As fast response is necessary to follow the sharp peaks in ultra-fast analysis, the RF-20A and the RF-20Axs provide 10ms response.
The quick response time permits ultra-fast LC without a loss of separation.
The simultaneous testing of multiple components requires detection at optimal wavelengths.
These detectors allow ultra-fast, sensitive, multi-component analysis using wavelength switching via a time programme.
The RF-20Axs also features a temperature-controlled cell with a cooling function.
This maintains a constant detector cell temperature, even if the testing environment's room temperature fluctuates, ensuring reproducibility without any drop in sensitivity.
To facilitate maintenance, each detector's xenon lamp and flow cell can be replaced at the front panel.
According to Shimadzu, the standard flow cell or semi-micro flow cell can be replaced without any tools.
The xenon lamp life has been extended to 2,000 hours - four times longer than previous Shimadzu lamps.
Specialised application systems for amino acid, reducing sugar and carbamate pesticide analysis are also available with the RF-20A and RF-20Axs detectors.
