Fields of Expertise: Advanced Material Analysis via Raman & IR Spectroscopy


At ViefhausAnalytik, we apply high-resolution Raman and Infrared (IR) microspectroscopy to solve complex analytical challenges across industry, research, and cultural heritage. Our methods are non-destructive, precise, and often conducted on-site using our self-developed portable Raman system.

We specialize in identifying unknown substances, characterizing material changes, and supporting quality assurance — from automotive engineering to archaeological conservation.

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.
