Raman spectroscopy

Obtain information about the molecular structure and crystal structure of the sample.

Raman spectroscopy is a technique that utilizes the phenomenon of light scattering (Raman effect), where the frequency of incident light changes as a result of interaction with molecules, to obtain information about the structure within molecules. - It is possible to obtain information about the molecular structure and crystal structure of the sample. - By using laser light, it can measure smaller areas compared to FT-IR (beam diameter approximately 1 μm).

basic information

Raman scattering is the phenomenon where light of a different wavenumber ν, corresponding to vibrational energy, is scattered in response to incident light with wavenumber ν0. In Raman spectroscopy, by detecting the Stokes Raman light emitted at a different wavenumber ν from the incident light, a spectrum can be obtained, allowing for the identification of the vibrational modes of atomic groups contained in the sample and providing information about their bonding states.

[MST Homepage] Analysis Case "Evaluation of Bone Condition Before and After HF Treatment" has been published.
- Product news
We have published analysis cases on the MST homepage. ◆Title Evaluation of Bone Condition Before and After HF Treatment ~Evaluation of Condition Before and After Chemical Treatment Using Raman Analysis~ ◆Measurement Method / Processing Method Raman / Chemical Treatment ◆Product Field Pharmaceuticals / Biotechnology ◆Analysis Purpose Evaluation of Chemical Bonding State ◆Overview HF (hydrofluoric acid) is widely used in processes such as wet etching of SiO2 and plays a very important role in semiconductor manufacturing. However, it is also a very dangerous chemical that can penetrate the skin and damage bones, requiring careful handling. The erosion of bones caused by HF occurs due to the reaction between Ca, which exists in bones as apatite, and HF, resulting in the formation of CaF2. This case introduces an evaluation of the changes in this reaction using Raman analysis. ★★For detailed data, please see the link★★
