Instructions for using Raman spectrometer

Sample preparation: Ensure that the sample has a certain degree of transparency. For example, solid samples may need to be prepared as thin films on non transparent substrates, while liquid samples can be directly measured. Keep the sample dry and clean to avoid interference from impurities in spectral measurement.

Instrument parameter setting: Set instrument parameters according to actual needs, including laser wavelength, power, incident angle, spot size, etc. Different samples may require different parameter settings, so adjustments need to be made according to the actual situation.

Measurement: Place the sample in the measurement scene of a Raman spectrometer for spectral measurement. The Raman spectrometer will automatically scan a certain range of frequencies, record the intensity of scattered light, and analyze the structure and composition of the sample through the observed spectrum.

Data processing: After obtaining spectral data, data processing can be performed to obtain more accurate results. Common data processing methods include spectral peak recognition, data fitting, background removal, etc. Specific data processing methods can be selected according to actual needs.

Cleaning and shutdown: After the experiment, clean the sampling table and related optical components in a timely manner to prevent errors in the next experiment results caused by sample residue. Finally, turn off the power of the Raman spectrometer, log out of the software account, and perform the shutdown operation according to the requirements of the device.

Through the above steps, Raman spectroscopy can be effectively used for spectral analysis, providing valuable information and data for scientific research and industrial applications.
