GFK25Our analytical labs are equipped with state-of-the-art equipment for material analysis, which is used for the comprehensive characterization of substances. A corresponding sample preparation is guaranteed by our experienced staff.

Thermal analytics

The method of differential scanning calorimetry (DSC) is used to determine the melting temperature, the glass transition temperature, as well as the enthalpy change during melt, crystal transformations and chemical reactions.
Another thermal analysis, thermal-gravimetric analysis (TGA), is used to determine the change in mass as a function of temperature and/or time. This measuring method is used, among other things, to quantify the amount of fillers (carbon black, chalk, glass fibers or other inorganic fillers), the decomposition behavior and to determine drying times for substances containing water or solvents.


Infrared spectroscopy (FTIR) is used to identify unknown samples by comparison with spectra from a database or for quantitative analysis of samples. The plastics to be examined can be present as part, film, plastic granulate or powder to be identified.
UV/VIS spectroscopy can be used to investigate damage to plastics, color pigments and paints. Often the decomposition of plastics already begins under the influence of daylight. This becomes apparent by embrittlement or discoloration, which can be prevented by suitable material selection and resistant pigments.

Gas chromatography with mass spectrometry

In gas chromatography with mass spectrometry coupling (GCMS), the gas chromatograph is used to separate the mixture of substances to be investigated and the mass spectrometer to identify and, if necessary, quantify the individual components.


Rheometer-Haake-Mars-001-kA rheometer can be used to measure the flow properties of fluids in relation to different mechanical loads and temperatures. For example, it provides insight into the viscosity and dilatancy, which are measures of toughness during flow. This can be used to follow the curing of adhesives or to characterize the melting of thermoplastics. Statements can also be made about thixotropy and intrinsic viscosity, as is the case with fluids which change their flow behavior greatly with load. This is of particular interest when using paints and varnishes which can be spread and sprayed but should not drip or run afterwards.


Lasermikroskop-Platine-001-kHigh-resolution digital microscopy can be used to analyze the finest structures and combine different levels of an object to form a 3D image. Digital technology makes it possible to create images with continuous depth of focus. A lens with a swivel stand and 20 to 100x magnification enables the creation of all-round views. For higher magnifications, a lens with 200 to 1000x magnification is also available.
