When a gas, liquid or transparent sample is irradiated with monochromatic light with a wavelength much smaller than the particle size of the sample, most of the light will be transmitted, while a small part will be scattered at different angles, resulting in scattering.
In addition to Rayleigh scattering with the same frequency as the original incident light, there are a series of Raman spectral lines that are symmetrical and distributed with several very weak rays that are shifted from the frequency of the incident light. This phenomenon is called the Raman effect. Since the length of the Raman spectral line is directly related to the vibration or rotation energy level of the sample molecule, information about the vibration or rotation of the molecule can be obtained.
Portable X-Ray fluorescence - Raman instrument is an integrated analysis instrument designed by LANScientific for user needs. It is a combination of XRF technology, Raman spectroscopy technology and scientific stoichiometry algorithm, with small size, simple preparation/no sample preparation, short determination time, high sensitivity, wide analysis range, low cost characteristics, chemical research, polymer materials, biomedical. Pharmaceutical testing, gem identification and other indispensable analysis equipment.
