The sky is not the limit
In difference to many other industries, molecular contamination, bake out of components for dry cleaning and component testing have long played an important role in aerospace:
- The ECSS standards recommend residual gas analyzes and / or TQCM measurements to detect molecular contaminations
- Baking under vacuum is required to optimize the fine and ultra-fine cleaning of components and to release the last traces of the organics under the simultaneous influence of vacuum and temperature from the surfaces
- Thermal vacuum chambers are used to expose components to ambient conditions in space for the parameters pressure and temperature to test and qualify them.
With the help of our systems, you can perform the above-described analyses, cleanings and tests close to the process. All TREAMS systems are united by a high level of integration, automation and intuitiveness.
What means molecular contamination?
Molecular or film type contamination is a thin, coherent (non-particulate) layer of undesirable, foreign components on partial or full surfaces of components.
Sources and examples for molecular contamination
Using a standardized process chain, we have listed possible sources of contamination that should not be underestimated. Components can be contaminated from incoming goods through production, cleaning and finishing to outgoing goods and the choice of packaging.
