Questions and problems we solve
Whether lacquers or coatings adhere is largely determined by the chemistry on the surface. However, the function of layer systems, such as the reflection properties of optical systems, is also influenced by the composition and layer structure.
What is on the surface? How much and where?
Many analytics devices are already failing if they are just trace elements.
Would not it be nice to have analytical methods that are sensitive and non-destructive?
After an XPS, TOF-SIMS and Auger analysis, you can continue to use your samples without hesitation.
Manufacturing processes use lubricants, release agents, coolants, grinding and polishing agents. In between, protective films and passivations are used. The wettability in later production steps is often strongly influenced by residues after cleaning processes. Properties of electrical contacts, such as resistance and contact force are influenced by residues on the contact surfaces.
Joining properties (gluing, soldering, welding or bonding) are further aspects for the efficient production of products. In the case of polymer casting processes, good separability of the tools from the component is important, with the removal of the release agent again being important for the following process steps. How do you analyze in the nanometer range whether these release agents are actually removed?
Direct surface chemistry is crucial in catalysts and also in many sensors. For example, the oxidation state of metallic catalysts is an important aspect here. Sensors are found in exhaust systems, but also in medicine. Here are usually substances, functional groups and bonds on the surface of the function-giving elements.
If the function of a component is disturbed during operation, often causes from sources of the environment are the cause. Even aging of protective layers lead to changes in properties. The error analysis of the quality department is needed here for root cause research and if their available analysis methods are no longer sufficient we can support them.
Gaining knowledge about competitors’ technologies is another reason for using our highly sensitive methods in reverse engineering.
In all these areas we successfully use the combination of XPS, TOF-SIMS and AES. The nature of your question is unlimited.
