News - Introduction to Raman technology

I. Raman Spectroscopy principle

When light travels, it scatters off on the molecules of material. During this scattering process, the wavelength of the light, i.e. the energy of the photons, may change. This phenomenon of energy loss after scattering of photons to change the wavelength is called Raman scattering, and different molecules will cause different energy differences. This particular physical phenomenon was first discovered by the Indian physicist Raman, who won the Nobel Prize in Physics in 1930.

Raman is a molecular spectroscopy technique, just like a human fingerprint, each molecule has its own unique spectral characteristics, so the rapid and accurate identification of chemicals can be achieved through the comparison of Raman spectra..

II. Raman spectrometer introduction

A Raman spectrometer generally includes several parts such as a laser light source, a spectrometer, a detector, and a data processing system.
Although Raman technology has played an important role in chemical structure analysis in the first few decades of its discovery due to problems such as weak signals, it was not gradually used more widely until the emergence of laser technology in the 1960s..

As a leader in the field of portable Raman research, JINSP COMPANY LIMITED has a variety of devices, which enable rapid, non-destructive identification of chemicals on site through a rich built-in database and specialist identification algorithms. For more professional users, devices and methods such as micro-Raman and quantitative studies of chemical reaction process can also be provided.

III. Raman spectrometer features

1. Rapid analysis, with detection within seconds.
2. Easy analysis without sample preparation.
3. Non-destructive, in-situ, on-line detection without contacting the sample.
4. No interference with humidity, no interference with high and low temperatures and high pressure;
5. It can be combined with a microscope to achieve accurate identification of chemical components at specific sites; ;
6. Combined with chemometrics, it can realize the quantitative analysis of chemical substances.
