What is Raman Spectroscopy?

Raman spectroscopy is well recognized as a powerful tool for the chemical and structural identification of materials in the solid, liquid or gas state

For a qualified scientific identification expert, the phrase of “To do a good job, one must first sharpen one's tools” means that someone have to keep updating the knowledge and technology of scientific identification devices. In the recent years, the most popular device is Raman spectrometer. The main reason is Raman spectrometer can accurately and rapidly solve many scientific identification problems that cannot be easily solved using traditional methods in practice. With the great improvement of Raman spectroscopy technology, the advanced portable model has been also developed. Its high sensitivity and stability performance can be compared with the research level model in a laboratory. Hence, the portable Raman spectrometer has become the new favorite tool in the applications fields of scientific identification. Currently, Raman spectrometer is quite famous instrument in spectra analysis. Most of scientific identification teams and teaching centers all over the world have already had Raman spectrometers instrument.

Raman spectroscopy technology has been widely applied in scientific identification. Depending on the identification projects, the specifications of a Raman instrument are varied. There are five major specifications that will affect the performance of a Raman instrument:

  1. laser source and power

  2. software and analysis algorithm

  3. sensitivity

  4. resolution

  5. microscopy and detectors.
