Raman Microscopy analysis laboratory
You want to analyse your materials using Raman microscopy
What is Raman microscopy ?
Raman microscopy or micro Raman is a spectroscopic analysis technique based on the Raman effect, an inelastic light scattering phenomenon. This technique is used to identify chemical compounds, characterise materials and analyse their structures on a microscopic scale.
Raman microscopy (μ-Raman) is a combination of conventional microscopy and unique chemical identification using Raman spectroscopy.
When these two techniques are combined, they offer the possibility of chemically analysing small samples and allow spectral information to be linked to spatial information.
How does Raman microscopy work?
Raman microscopy analysis is based on the Raman effect, which occurs when light is scattered by a molecule and changes frequency according to molecular vibrations. It consists of a heating stage that can be set from -180°C to 600°C. It combines a microscope with a Raman spectrometer to obtain detailed information on the chemical composition of samples on a microscopic scale by providing chemical imaging.
What are the main uses of Raman microscopy ?
Micro Raman analysis is widely used in fields such as chemistry, materials science and pharmaceutical research, for the analysis of organic and inorganic substances.

FAQ
Raman spectroscopy has several significant advantages over other vibrational spectroscopy techniques, such as infrared (IR) or near infrared (NIR) spectroscopy. Unlike absorption spectroscopy, Raman spectroscopy is based on the inelastic scattering of light by a sample. This allows solids, liquids and gases to be measured directly without the need for complex sample preparation. What's more, analyses can be carried out through transparent materials such as glass or plastic.
Another major advantage of Raman spectroscopy is the low intensity of the Raman signal in water. This makes it easy to detect compounds dissolved in water, without significant interference.
The Raman spectrum provides information about all the molecules present in the sample being analysed. For example, spectra obtained from mixtures contain characteristic bands for each molecule. If the spectra of the different components are known, it is possible to deduce quantitative information about the composition of the mixture.
