In industries such as aerospace, medical and semiconductor technology, component cleanliness is one of the most important key factors for high-quality products and effective process chains. With ARGAT®, the automatic residual gas analysis tool and VIDAM®, the cleanliness measurement device for filmic contaminants, TREAMS defines today's standard for detecting and analysing filmic contaminants on and outgassing rates of components and assemblies. The focus is on process proximity, modularity, automation, intuitive operation and networkability. The systems, which are based on vacuum technology, make it possible to precisely determine the cleanliness and outgassing properties of critical components and to further optimise process chains with the help of these findings.
