The Chinese Academy of Geological Sciences added a high-resolution Raman spectrometer to the laboratory

the Institute of geology of the Chinese Academy of Geological Sciences has long been committed to the detection and analysis of strata and paleontology, rocks and minerals, deep earth and other substances. In order to meet the increasing research requirements, they recently purchased a LabRAM HR evolution new generation high-resolution Raman spectrometer from Horiba, which will be used to carry out the research on the structure and crystallization of zircon and other dating minerals

micro laser Raman spectrometer is a new micro area analysis instrument, which can analyze the mineral structure conveniently and non destructively. Through research, we can determine the composition and salinity of the fluid in the inclusion, and then provide an important basis for geological analysis. As far as geological researchers are concerned, they are most concerned about whether Raman spectrometer has the functions and configurations of hyperspectral resolution, confocal, 3D imaging, high-definition camera, etc. we will learn about them one by one below

hyperspectral resolution

hyperspectral resolution can obtain more accurate spectral peak positions, distinguish spectral peaks close to each other, and accurately capture small peak position frequency shifts. Therefore, we must pay attention to the changes of safety and half height width. LabRAM HR evolution is an instrument with the longest focal length (up to 800mm) in the single-stage Raman spectrometer, that is, the highest spectral resolution. It is very suitable for mineral composition identification, stress, crystallinity, defects, polymorphs and other analysis

confocal

labram HR evolution is a confocal Raman spectrometer, which adopts pinhole true confocal design (as shown in the figure below). By installing a fully adjustable confocal pinhole aperture on the optical path, if there is an emergency Raman signal outside the focusing area, the spatial resolution of micron level can be achieved

3D imaging

researchers can also understand the three-dimensional spatial distribution of minerals through 3D imaging. As shown in the image of CO2 inclusions in the figure below, the water and CO2 contained in quartz minerals can be visually observed through various adjustment functions such as rotation, transparency and cross section

HD camera

3million pixel color HD camera infinity2 has very high sensitivity and resolution to the ups and downs of Turkey's political situation, but there is no clear strategic mineral directory to take very clear microscopic images
