Bruker Senterra micro-Raman spectrometer

Our equipmentAnalysis and characterizationPhysicochemical analysis & Spectroscopic

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 chemical bondings 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.

  • 2 excitation laser sources are available: 532 nm and 785 nm.
  • Spectral range: from 70 to 4000 cm-1
  • Spectral resolution: 3-4 cm-1
  • Lateral resolution 2-3 μm
  • Depth resolution 2μm
  • Motorized XY stage
  • Heating plate (-180°C to 600°C)

Avantages

  • Analysis method that does not require special sample preparation
  • Identification of molecules using numerous spectral databases.
  • Confocal microscopy: depth profile
  • Possibility of carrying out chemical maps
  • Analysis of microscopic details or inclusions.
