| Definition | A high-sensitivity fluorescence spectrometer used to identify and quantify trace-level components of liquid samples, for applications such as food, pharmaceutical and environmental analyses. The fluorescence detector uses the principle of Raman spectroscopy to excite the liquid sample with excitation light from a Xenon lamp, and breaks up the emitted fluorescence light with a fluorescence monochromator. It extracts the required fluorescence wavelengths and measures the intensity with a photomultiplier. The RF-20A is capable of ultra fast, high-sensitivity multi-component analysis using a wavelength switching by time program, and utilises a four-wavelength measurement function that detects each component at its optical wavelength. Optional additions include an Amino Acid Analysis System, a Reducing Sugar Analysis System, a Carbamate Pesticide Analysis System and a Synthetic Antibacterial Agent/Mycotoxin Screening System. The RF-20A achieves a water Raman S/N ratio of 1200, and the Xenon lamp lasts approximately 2000 hours. It also has a 10 ms response time, and a wavelength range of 0, 200 nm to 650 nm. | ||
