The chiral Raman spectrometer collects the scattered light that produces frequency changes and analyzes their frequency variations. Due to the specific vibration modes of different chemical bonds or functional groups, each substance has a Raman spectrum. Just like human fingerprints, these spectra can serve as "molecular fingerprints" of substances, used to identify different molecular structures. For chiral molecules (i.e. molecules that cannot overlap with their mirror image), their response to left and right circularly polarized light is different. By utilizing this characteristic, it is possible to distinguish and quantitatively analyze the excess of enantiomers in the sample, without the need to separate enantiomers, which can be directly measured.

Precautions for using chiral Raman spectrometer:

1. In terms of safety protection

-Ensure that the laser is turned off before performing sample replacement and other operations, and avoid direct exposure to the eyes or skin, as the laser has strong energy and may cause serious harm to the human body. At the same time, attention should be paid to avoiding the laser beam from shining on flammable and explosive substances to avoid causing danger.

-During the use of the equipment, appropriate personal protective equipment such as lab coats, gloves, and goggles should always be worn.

2. Environmental condition control

-Maintain the stability of the laboratory environment, including factors such as temperature and humidity. Generally speaking, the use effect is better when the room temperature is between 15-30 degrees Celsius and the relative humidity is between 40-70 degrees Celsius. Avoid using instruments in various environments to avoid affecting their performance and measurement accuracy.

3. Sample processing specifications

-The sample should be clean, dry, and free from impurities as much as possible. Impurities may interfere with the signal of Raman spectroscopy, affecting the accuracy of analysis results. For different types of samples, they should be processed and prepared according to the correct methods to ensure the reliability of the measurement.

4. Instrument maintenance and upkeep

-Regularly clean and maintain the instrument, especially key parts such as optical components and detectors. You can use a clean soft cloth to gently wipe and remove dust and stains.

-Perform regular calibration and maintenance according to the requirements of the instrument manual to ensure that all performance indicators of the instrument meet the requirements. It is recommended to develop detailed maintenance logs that record the time, content, and results of each maintenance, which will help track equipment status and provide reference for future maintenance.

5. Follow the operating standards

-Strictly follow the operating procedures of the instrument and do not arbitrarily change settings or attempt unauthorized functions. During the measurement process, it is necessary to maintain the stability of the instrument and avoid data deviation caused by vibration or movement.

-If encountering abnormal situations or malfunctions, the measurement should be stopped in a timely manner and professional technicians should be contacted for repair. Do not disassemble or repair the instrument by yourself.
