Fluorescence spectroscopy :

Fluorescence spectroscopy Fluorescence spectroscopy is a type of electromagnetic spectroscopy which analyzes Fluorescence from a sample

Fluorescence spectroscopy :

Fluorescence spectroscopy Fluorescence spectroscopy is a type of electromagnetic spectroscopy which analyzes fluorescence from a sample. In the spectrometer Fluorescence absorb the material to be studied photons of light which leads to a stirring case of electronic stable to one of the cases in different vibrational state electronic raised

Fluorescence spectroscopy :

Fluorescence spectroscopy Generally light passes issued by the excitation source excitation source through a unified candidate or waves and collides with the sample, the sample absorbs part of the incident light and incident light fluorescence is happening to some of the particles in the sample

Instrumentation :

Instrumentation Energy Source • Excitation monochromator • Sample cell Emission monochromator Detector Recorder  

Instrumentation :

Instrumentation   Light source : You can use many sources of light and thrills including : 1-Lasers 2-Mercury Lamp

Instrumentation :

Instrumentation monochromator 1-Excitation monochromator 2-Emission monochromator   There are two types of Fluorescence spectrometer, first: - the so-called 1-filter fluorometers , and the second type is called: - 2-spectrofluorometers

Instrumentation :

Instrumentation Detector detector placed on two wavelongth 1-Excitation monochromator 2-Emission monochromator Detector maybe multi-channeled single-channeled

A general schematic:

A general schematic

Application :

Application There is a relatively small number of compounds that have a characteristic Fluorescence such as Aromatic hydrocarbons This has contributed to the use of t he spectroscope successfully in the detection of many of 1-organic compounds, 2-aromatic numerous active substances in drugs and

Application :

Application 3- uses a Fluorescence spectroscopy in the field of research chemicals, biochemical, and medical analysis of organic compounds 4- also used in skin tumors distinguish benign and malignant
