Fluoresence Detector

RF-20A/RF-20Axs

Utilizing a newly designed optical system, the RF-20A and RF-20Axs offer world-class levels of sensitivity. A water Raman S/N ratio of at least 2000 for the RF-20Axs and 1200 for the RF-20A makes these detectors powerful tools for analyses demanding the detection of trace-level components. The diagram at right shows an example of the ultra-high-sensitivity analysis of anthracene. A S/N ratio of 21.5 was achieved for an injection of 10.48 fg anthracene (RF-20Axs). This is equivalent to approx. 1.5 fg limit of detection (S/N ratio = 3), which is excellent.
