Error diagnosis with microscope and X-ray beams

Our portfolio of microscopic, thermal, spectroscopic and mechanical analytical methods provide high-resolution images with precise information for the chemical identification of organic and inorganic materials.

Optical microscopy offers a wide variety of lighting techniques that provide a contrast effect, such as reflected light, transmitted light and fluorescence.

In addition to detecting inorganic materials, analytical scanning electron microscopy (SEM) coupled with transmission electron microscopy (STEM) and element analysis (EDX) makes it possible to take measurements in a high vacuum, a low vacuum and in a humid sample chamber (ESEM). Depending on the material, a resolution of 1-10 nm can be achieved using electron microscopy.

Optical spectroscopy like infrared, Raman and UV/VIS spectroscopy can help to identify your samples further by depicting the distribution of organic components (chemical imaging) and performing infrared spectroscopic analysis on diffusing gases according to temperature.

We can use atomic force microscopy (AFM) to determine the topography and to quantify local material properties like stiffness and adhesion.

Nanoindentation is an instrumental hardness measurement process that supplements our portfolio of micromechanical material testing services.

X-ray diffraction (XRD) can be used to analyze crystalline and semi-crystalline materials without destroying them. The copper Kα radiation is used to detect surface defects and for spatially-resolved crystallinity determinations. It is also possible to analyze amorphous substances using three-dimensional computer tomography (CT)..

After a microscopic study, an automatic image analysis can be performed to identify the distribution of particle sizes or fiber lengths.

By combining these methods, we are able to offer custom tests and analyses on a wide range of issues.

Applications

Exact statements about the quality, morphology, microstructure, phase homogeneity and composition of your materials are a requirement for optimizing your processes and ensuring rapid troubleshooting when there are production problems.

Analytical issues arise in the plastics industry, such as the quality of thermoplastics, plastic pellets, molded parts (e.g. dashboards), hybrid components made of foams, fiber-reinforced polymers, rubbers, silicones, pigment powders, coatings and adhesives.

On the other hand, in the pharmaceutical sector companies often need tests to be conducted on active ingredient crystals, tablets, catheters, glass ampules, dialysis membranes or blister packaging.

Our portfolio also covers the testing of metallic materials or pigments.

Our microscopic procedures make it possible to view material-independent defects in the form of streaks, inclusions, bubbles or blisters – even right down to the smallest dimensions.

Furthermore, we will help you with any analyses relating to complaints, anti-counterfeiting and production monitoring. We customize the scope of the investigations to your needs.

Fast response, short processing times

The combination of modern analytical methods and expertise make it possible to have rapid response and processing times. Contact our analytics team or our experienced customer support staff directly, and they will connect you to the right specialist.

Analytical issues

Infrared spectroscopic analysis for the pharmaceutical industry - a quick look inside the tablet

We use infrared (IR) microscopy for many years. With our 16-fold detector, we are able to analyze organic compounds in the pharmaceutical industry, e.g. analyzing the molecular structure of a tablet.

Infrared spectroscopic analysis for the plastic industry - Knowing why things are not sticking

Via high-resolution infrared (IR) microscopy, we can determine why glued plastic foils separate over time.

Material analysis for tires - Revealing material composition through stitches

We determine through state-of-the-art quantitative atomic force microscopy (AFM) the local composition and get an insight high-resolution view of the material properties.

Nanoidentation - Hardness on a microscopic scale

Morphology and mechanical properties are important to decide where materials such as polymer blends, filled polymers and metals, or ceramics are used. The combination of nanomechanical measurement methods of nanoindentation with atomic force microscopy opens up new possibilities for material development and testing.

Defect analysis for pharmaceutical products

Medicinal products and their packaging require quick and detailed defect analysis. We can support you by identifying the causes of defects as part of our analyses, thus helping you eliminate them. You can use the knowledge gleaned from these tests to improve your production process.
