Molecular Fingerprint


on the molecular level

Why FT-IR analysis?

IR – spectroscopic investigations enable the determination of chemical structures in molecules and provide insights into the basic molecular configuration of an unknown probe. The analysed material can be liquid, pasty or even solid. Only extremely small sample quantities are required. Thus, an excellent identification of singular substances and combinations is possible.

Material analysis by FT-IR spectrometry - How it works

How do material analyses by FT-IR spectrometry work ? This can be explained in three steps. Each material has a very unique molecular fingerprint. This fingerprint can be identified by analyzing the material.

Performance spectrum


  • Measuring the molecular fingerprint
  • Reference measurements for quality monitoring
  • Traceable proof of quality


  • Chemical components e.g. additives or foreign substances
  • Thermal and chemical stress
  • Oxidation, degree of cross-linking and moisture absorption


  • smallest concentrations > 1% of the searched substance detectable


  • Variances from the ideal profile are immediately detectable
  • Trouble-free production process
  • Reduced waste
