Model 93 Fluorescence spectrophotometer is designed for high sensitivity and selectivity. The measuring sensitivity is 2-3 times higher than an average UV-VIS spectrophotometer. The Model 93 provides measurement of excitation & emission spectra, intensity, lifetime and fluorescence polarization. The design features a Czerny-Turner manual monochromator and a photomultiplier detector. ations Pharmaceutics & pharmacology: pharmaceutical quality control and metabolism research Biochemistry: quantitative minute substance measurement in biological samples Food industry: measurement of trace components in food Pollutant analysis: air pollution analysis, environmental hygiene detection and food pollutants analysis Organic & inorganic chemistry: analysis of trace components which cannot be measured with absorptive spectrophotometer Features Special light source with high brightness and long service life (longer than high-pressure xenon lamp and high-pressure mercury lamp) Low noise and high sensitivity with a high-performance Hamamatsu photomultiplier Instrumental S/N can reach to 1×10-9/ml (quinine sulfate) Good thermal stability
