Bruker Senterra micro-Raman spectrometer
Raman spectroscopy is a non-destructive method for characterizing the molecular composition of a material. This is a complementary technique to infrared spectroscopy. Both spectroscopies make it possible to study the vibrational modes of a molecule, but the selection rules can be different depending on the molecular symmetry. This is why some connections may not be detected by either method.
Coupled with a confocal optical microscope, it allows analyzes to be carried out with a spatial resolution close to one micron.
