Particle monitoring to monitor particle pollution

Particle monitoring is a method of residual dirt analysis for the continuous monitoring of particle pollution in specific environments, such as production areas, clean rooms, warehouses or assembly processes. The aim of particle monitoring is to guarantee air and surface cleanliness and to ensure that the specified standards for technical cleanliness are adhered to in order not to endanger the function and quality of sensitive components. Special particle traps are often used to capture particles from the air and sediment them on an adhesive layer. A particle stamp offers a supplement to the particle trap.

Particle analysis during series production
in the laboratory

The analysis during series production is carried out during series production in order to continuously monitor the particle load of components and assemblies and to ensure that specified cleanliness standards are adhered to. The checks are carried out in accordance with VDA 19 based on particle size distribution and gravimetry. For this purpose, random samples are taken and measurements are carried out during series production. This type of residual dirt analysis minimizes the risk of contamination and ensures that the end products function properly.

Particle trap

Our particle traps capture air particles from the environment at the installation site and enable a correlation to the actual particle load on surfaces. Possible installation locations:

Production
Warehouse
Individual machines

The particle trap consists of an adhesive layer that absorbs and sediments particles. Before activation, the adhesive layer is protected with a protective film. A lid closes the particle trap and serves to protect the sedimented particles after deactivation. The average laying time is between 7-10 days.

The particle traps are evaluated in the course of the residual dirt analysis using an automatic microscope including detailed documentation. A standardized value is also output here, the so-called Illig value, which serves as a comparison number or uniform size number according to VDA 19 Volume 2.

Particle stamp

The particle stamp is an ideal addition to the particle trap and enables particles to be captured quickly and easily without the need for complex wet extraction. This allows contamination to be identified and assessed quickly, allowing a quick statement to be made about the degree of contamination. The particle stamp is therefore an efficient and cost-effective addition to residual dirt analysis.
