Method Background

Analytical investigations of industrial products and samples are a central and essential part of quality management, for example FMEA (Failure Mode and Effects Analysis), optimization and diagnostics.

Raman and Infra-Red spectroscopy combine essential advantages:

 

  • The samples do not get chemically and physically changed
  • Only a few milligrams or some drops of a substance are necessary for analysis
  • Particles down to size of 1-2 micrometers can be analyzed
  • Short measurement time (2 - 5 seconds for a single shot)

 

Technical aspects:

  • Lasers with different wavelengths (532 and 638 nm) and variable laser power
  • chemical imaging and automated XYZ mapping.
  • Infrared spectra in diffuse reflectance and transmission mode (KBr pellets and cuvettes).
  • Building measurement cells to research on chemical and physical reactions and changes of the sample.

 

Therefore we can provide a comprehensive spectroscopic view on the sample influencing factors.
