Highend Fluorescence Detector for Liquid Chromatography
200 – 750 nm, fluorescence detector, including accessories
The fluorescence detector RF-20Axs provides world-class sensitivity, excellent maintainability and diverse validation / support functions. It supports a wide range of applications in the wavelength range of 200 to 750 nm from conventional analysis to high-performance analysis. With a signal-to-noise ratio of 2000 for the water-Raman band, the fluorescence detector is very well suited for trace analysis.Measuring cell tempering ensures the lowest possible noise and drift values.
The integrated low-pressure mercury lamp allows easy wavelength accuracy verification. The xenon lamp and flow cell are directly accessible on the device, thus allowing a quick and easy handling and maintenance of the device by the user, thereby minimizing downtime. The lamp life is 2000 hours. When replacing the xenon lamp, no adjustment is required.
- Temperature controlled optical unit
- Pressure resistant flow cell
