Fluorescence spectrophotometer features and application

Features 1. Fluorescence Emission Spectroscopy Select a certain wavelength of light to excite the sample and record the functional relationship between the fluorescence emission intensity and the emission wavelength in the sample. The fluorescence emission spectrum is obtained.

2. Fluorescence excitation spectrum selected a fluorescence emission wavelength recording fluorescence emission intensity as a function of the excitation light wavelength, that is, fluorescence excitation spectrum.

3. Time resolution technology;

It can be used to distinguish and separately measure the components of the mixture that have spectral overlap but have different life spans.

The time-resolved fluorescence measurement formula is as follows:

P(t)=P0EXP(-t/Ï„)

Where P(t): fitting exponential function P0: intensity value EXP: exponent operator t: time value Ï„: fluorescence mean time lifetime product application The material composition analysis can be applied to biochemistry, biomedicine, environmental chemical and other departments.
