Excitation and Emission Spectrum Fluorescence Spectrophotometer
Fluorescence analysis can provide information including excitation and emission spectrum, emission light intensity and measurement of life of emission light and polarization fluorescence etc and a wide lineal range of working curve.
This method has been used in: Medical science and clinical ,Pharmaceutical science and pharmacology,Biochemistry ,Food industry, Pollution and Organic and inorganic chemistry.
Features :
1.Two operation modes fluorescence intensity and luminous intensity.
2.365nm exciting wavelength,Raman peak of water S/N ≥150.
3.10 stages emission spectrum scanning, including high speed low S/N scanning and precise scanning. Total spectrum scanning could be done in 1 second. With the intelligent prescanning feature, unknown sample"s spectrum information could be detected rapidly. Auto-omission of the influence of scattering peak and harmonic peaks, it ensure the best measurement parameters and locate the fluorescence emission peak.
4. Support off-line mode and on-line mode. Under off-line mode, instrument"s computer system offer the fluorescence intensity measurement,
concentration direct reading, auto 0 adjustment, auto background subtraction and etc. Under on-line mode,we could use quality and quantity software to control data acquisition and analysis through USB2.0 interface.
5. High stable and long life 150W xenon lamp and power source ensure high stable testing and wide range of spectrum.
6. The normalized feature for fluorescence value could make different fluorescence"s result comparable.
7. Provide optional PC qualitative and quantitative software package with expansible time scanning,wavelength scanning, graphic calculation and storage-access abilities.
8. Optional accessories for different measurement, including single hole cell holder, fluorescence sample holder for different features, 200μl microscale centrifuge tube, micro scale capillary sample holder, semi-auto sample introduction accessories, membrane sample accessories, powder sample accessories, jacket sample accessories.
