Precautions for using Raman spectrometer

Safe operation:

Ensure that the laser is preheated before use to achieve better testing results.

Before opening the Raman spectrometer, first open the cover of the Raman probe and ensure that the probe is not facing a person.

Wear protective goggles during use to avoid direct eye contact with the open Raman probe.

When operating software, avoid quick or frequent operations, such as scanning the background, wait for 1-2 seconds before clicking the run button.

When conducting custom measurements in the laser constant light mode, fix the probe to avoid accidents and try to avoid the laser being in a constant light state for a long time.

Instrument maintenance:

Regularly clean the end face of the Raman probe, keep the window clean, and avoid contamination that may affect the testing results.

After use, cover the protective cover of the Raman probe and store it properly.

After turning off the laser, let the cooling fan continue to run for 1-2 minutes before turning off the main power to help dissipate heat from the device.

Sample processing:

Before testing, ensure that the surface of the sample is smooth and uniform, avoiding the attachment of impurities such as particles and dust.

For liquid samples, try to avoid the generation of bubbles and precipitates as much as possible.

For solid samples, appropriate methods should be used to fix the sample on the optical platform to reduce the impact of external interference and sample motion on the measurement results.

Experimental operation:

Select appropriate spectral range, wavenumber resolution, and laser power parameters as needed.

Choose an appropriate spectral integration time to avoid excessively long or short integration times affecting the accuracy of the results.

Perform multiple measurements on the same sample and take the average to reduce experimental errors and random noise.

Data processing:

Use data processing software to perform post-processing on spectral data, such as noise filtering, baseline correction, and spectral smoothing, to improve signal-to-noise ratio and data quality.

Following these precautions can ensure the safe use of Raman spectrometers and the reliability of test results
