Particle content

Reduction of the concentration of particle numbers in defined ranges of sizes plays a decisive role for compliance with regulatory or internal specifications in the pharmaceutical industry. Nonetheless, process gases are frequently not being taken into account, although they might have direct contact with the product and are streaming in clean rooms of all classes.

This necessarily leads to the requirement of testing process gases for their particle content, because they can potentially compromise clean room classes and finally product quality as well. DPhE conducts measurements for you according to EU-guidelines or DIN EN ISO 14644-1 using our self-developed expansion chamber and a downstream optical particle counter to determine the particle content in process gases.
