Fluo-Imager™ is a multipurpose spectral analyser aimed at the express detection and identification of organic compounds in liquid samples. Its operation is based on the techniques of spectral fluorescence signatures (SFS) and pattern recognition. With these techniques different compounds in a mixture can be identified and quantified without the physical separation of individual substances in a sample.
Fluo-Imager™ is capable of performing both absorption spectra measurements and capture SFS simultaneously.
Spectral Fluorescence Signatures
The principle of SFS is based on the measuring of the fluorescence intensity of a sample at different excitation and emission wavelengths. The intensity of light induced fluorescence as a function of excitation and emission wavelengths constitutes a 3-dimensional fluorescence matrix of the sample. Such matrix is called the Spectral Fluorescence Signature.
Since various chemical substances have different characteristic excitation and emission spectra of fluorescence, they typically produce different spectral patterns in SFS, which are used for substance identification. The intensity of fluorescence serves as a measure of substance quantity.
