Spectroscopic Tests

Within the scope of spectroscopic tests, a radiation spectrum emitting from an exited specimen is energetically analysed. This information can be used for plastic and filler analysis. Thanks to the mostly very high spatial resolution and the small quantity of specimens required also local analyses of defects and other impurities are possible.

Our test methods include:

  • Infrared spectroscopy in transmission, reflectance or with attenuated total reflection (ATR) for analysing polymers and other organic substances (wave length range 4000 to 400 cm-1)
  • Infrared microscopy in transmission, reflectance or with attenuated total reflection (ATR), (mapping mode possible, resolution up to 20 µm)
  • Far-infrared spectroscopy (FIR), (wave length range up to 50 cm-1, heatable ATR sample table)
  • Energy dispersive X-ray spectroscopy (EDS) with Peltier cooled detector (SDD), combined with field emission scanning electron microscope (FESEM) for the spatially resolved qualitative and semi-quantitative analysis of the element composition of a large variety of samples
