In medical technology, the concept of purity has been deeply rooted for many years and is codified in regulations. Nevertheless, there are recurring problems that can be attributed to a lack of product purity. There are also aspects of production technology where excessively high purity requirements…
1. Introduction
Many materials and building materials can contaminate a pure production environment due to their properties and are thus a significant factor in achieving and maintaining the required purity.
Emissions from a joint of a handling unit can release microscopic particles that may contamina…
From mid-September, the Fraunhofer IPA will have the purity-optimized laboratory "CleanLab 2020" available to address, among other things, the following cleanliness-related topics using state-of-the-art laboratory infrastructure:
Cleanliness Analyses
- Cleanliness analysis of automotive components for…
The manufacturing of many products today must be carried out with consideration of cleanliness aspects, starting from computer chips, pharmaceuticals, implants to food and satellites. To meet the quality characteristic "purity," manufacturing often relies on cleanroom conditions. However, the cleanr…
1. Requirements for Particulate Purity
For integrated circuits manufactured in the semiconductor industry with feature sizes currently up to 22 nm, the high level of required particulate purity is immediately apparent. Particulate purity, meaning the absence of critical particles in the micrometer ra…

In a variety of innovative products, contamination control plays a crucial role. Despite the use of state-of-the-art cleanroom technology, critical contaminations in mass production cannot be completely ruled out. Therefore, the purity of contamination-critical products must be continuously monitore…
