High temperature Raman spectroscopy - HTRS
High temperature Raman spectroscopy - HTRS
Product details
The new technology of high-temperature Raman spectroscopy can be applied to various basic research work, including metallurgical slag, crystal growth, glass chemistry, geochemistry, functional materials and many other fields. Explore and reveal the changes and laws of the microstructure of substances at the molecular level with chemical composition and temperature under high temperature, as well as their interrelationships with the macroscopic properties of substances, and effectively promote the development of various new technologies and materials.
Technical difficulty: Due to the difficulty of background blackbody radiation in high-temperature Raman spectroscopy, necessary accessories need to be added to the experimental setup and detection methods need to be improved.
Solution: Microscopic Raman Time Resolution System
In high-pressure scientific research, some studies require samples to be placed at very high temperatures, in the range of 1500-5000K. The background blackbody radiation caused by the introduction is very strong, and the Raman spectral signal is completely submerged in the background blackbody radiation, making it impossible to obtain effective signal-to-noise ratio information. Time resolution method, using ns level shutter speed, collects Raman signals excited by pulsed lasers, and uses multiple chip accumulation methods to obtain good Raman information.
