The Museum of Natural History has at its disposal a number of state-of-the-art laboratories to perform the following procedures:

 

Electronic Microscopy and Microanalysis

Technical Staff
Maurizio Ulivi
Mario Paolieri

 

The interdepartmental service centre for Electronic Microscopy and Microanalysis (M.E.M.A.) of the University of Florence was estalished in 1989. In 2008, it has updated its instrumentation and now has at its disposal a ZEISS EVO MA15 microscope   equipped with OXFORD INCA 250 microanalysis .

The laboratory serves the Department of Earth Sciences, the Museum of Natural History and the Department of Industrial Engineering.

 

Raman and IR Microspectroscopy

Labs 
Via Gino Capponi 3r, Florence – ph. 055 275 6786 | 055 275 7537

Admin
Via La Pira 4, Florence – ph. 055 275 7572

The lab is equipped with a LabRam IR – Horiba Jobin Yvon spectrometer.

 

Description of the techniques

Raman Spectroscopy

Raman spectroscopy employs a quantum phenomenon (the Raman effect), whereby various materials diffuse a light radiation emitted by a laser source at different frequencies than that of the monochromatic incident bundle.

This spectroscopy is therefore a non-destructive technique, since the material being analysed is subjected to the action of a light source with no additional treatment (neither chemical nor physical) during the preparation of the sample. The presence of a motorized table allows Raman maps to be obtained.

 

FTIR Spectroscopy

The Fourier Transform Infrared (FTIR) spectroscopy is a particularly useful technique to investigate existing chemical bonds within the materials. When an infrared photon hits a molecule it can induce a change from a fundamental state to an excited vibrational state. Since the changes between vibrational states are typical of certain bonds and certain substances, this technique can recognize many substances.

The instrument works both in ATR (Attenuated Total Reflection) mode and in mirrored or diffused reflection mode.

General application fields of the techiques

Both techniques, being prominently complementary, allow the analysis of a wide array of substances, organic, inorganic, solid and liquid.

Applications
- Geological and planetological samples
- Artistic heritage
- Biological specimens
- Biomedical material
- Glass
- Polymers

This laboratory offers its services to third party users, such as other research institutes, private firms etc.
