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£ºClinical analysis of biological specimen.
3.Pharmaceutical science and pharmacology£ºAnalysis of natural pharmaceutical products; Quality control of pharmaceuticals and research of pharmaceutical metabolites.
4. Biochemistry£ºAnalysis of minute quantity of substances in biological body.
5. Food industry£ºAnalysis of minute quantity of constituents in food.
6. Pollution analysis£ºAtmospheric pollution, environmental testing and food contamination analysis.
7. Organic and inorganic chemistry£º Used in the trace analysis in case of those substances cannot be determined by absorption spectrophotometry.
