| Model 93 Fluorescence Spectrophotometer |
| Introduction |
|
The
S93 Fluorescent spectrophotometer is designed for high
sensitivity and selectivity. The measuring sensitivity of this
instrument is 2-3 times higher than that of a UV-VIS
spectrophotometer. The S93 provides measurement of excitation
& emission spectra, intensity, lifetime, and fluorescence
polarization. The design is based on a Czerny-Turner
manual monochromator and a photomultiplier detector.
|
| Applications |
- Pharmaceutics & pharmacology -- pharmaceutical quality control and pharmacon 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, food pollutants analysis.
- Organic & inorganic chemistry--Analysis of trace components which can not 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 slufate)
- Good thermal stability
