F93/F93A Fluorescent Spectrophotometer

Features:
1. The emission monochromator adopts 1200 line diffraction grating. Its large aperture and non-spherical reflecting mirrors produces extra high sensitivity.
2. High stable and long life xenon lamp and power source ensure high stable testing and wide range of spectrum.
3. EX light use LED,match with the central wavelength of 365nm、420nm、475nm、525nm narrow banding-ultra low back grounding precision filters to consist 4 set of EX  wavelength replacing system. The system can be replaced by customer,Carry on the maintenance expediently & can satisfy more choices and demand;
4. The central wavelength of 365nm、420nm、475nm、525nm narrow banding-ultra low back grounding  precision filters with low fluorescence background,it’s performance is better than glass filter;
5. LED is a cold-light source with longevity、lower background & reliability,prevent from thermo-pollution;
6. Automatic zero adjustment and automatic background subtraction;Eight stage sensitivity adjustment;Real time fluorescence reading display and concentration print out,Extra wide dynamic range of fluorescence reading,accurate measurement of minute changes in samples;
7. RS-232C serial port interface attached,after option Data Processing Software Package it is convenient to store record & transmit data & draw up a standard operating curve;
8. Quality fine,less weight & measure,test simply,particularly suitable for Edu. & Lab.

Applications:
1. Fluorescence analysis is a high sensitive and high selective sophisticated analytical method. This method can provide information including excitation and emission spectrum, emission light intensity and measurement of life of emission light and polarization fluorescence etc. This method can provide a wide lineal range of working curve. It has becoming an important analytical method in the region of trace analysis. This method has been used in:
2. Medical science and clinical analysis:Clinical analysis of biological specimen.
3.Pharmaceutical science and pharmacology:Analysis of natural pharmaceutical products; Quality control of pharmaceuticals and research of pharmaceutical metabolites.
4. Biochemistry:Analysis of minute quantity of substances in biological body.
5. Food industry:Analysis of minute quantity of constituents in food.
6. Pollution analysis:Atmospheric pollution, environmental testing and food contamination analysis.
7. Organic and inorganic chemistry: Used in the trace analysis in case of  those substances cannot be determined by absorption spectrophotometry.
