High Speed and Accuracy, Meeting a Variety of Measurement Needs ——ATF4500 Fluorescence Spectrophotometer

What is a Fluorescence Spectrophotometer?

Fluorescence spectrophotometers are instruments used to provide information on the properties and structure of molecules. Its principle is to scan the fluorescence spectrum emitted by liquid-phase fluorescent markers and provide many physical parameters including excitation spectrum, emission spectrum, fluorescence intensity, quantum yield, fluorescence lifetime, fluorescence polarization, etc., reflecting the bonding of molecules from all angles and structural conditions. By measuring these parameters, not only general quantitative analysis can be done, but also the conformational changes of molecules in various environments can be inferred, thereby clarifying the relationship between molecular structure and function. It can be used for spectral scanning of liquid and solid samples.

Fluorescence spectroscopy is an effective means to study the properties of fluorescent molecules and is widely used in fields such as new materials, life sciences, environmental sciences, edible science, meteorolgy,and geology . Fluorescence spectrum is divided into steady-state and transient fluorescence spectrum. Steady-state fluorescence spectrum excites the sample with continuous light and records the emitted light intensity to realize the study of sample characteristics; transient fluorescence spectrum uses picosecond pulses as the excitation light source and counts single photons to obtain the sample transient characteristics.

The three-dimensional fluorescence spectrum chart can intuitively reflect the optimal excitation wavelength and emission wavelength of the sample. Its three-dimensional chart or contour chart is also commonly used to identify each sample. It is widely used in criminal identification, water quality testing, petroleum testing, agricultural product identification and food checking.
