Resuspension Experiments of Cleanroom Particles

What is it about?

This work underscores the significance of the adhesion force of particles commonly found in clean rooms in their resuspension. Humidity-sensitive space instruments are "flushed" to reduce the amount of residual water inside the cavities. This injection of inert gas can lead to the resuspension of particles, which, during transport, can deposit on sensitive surfaces such as mirrors. Consequently, an initially unpolluted surface becomes polluted following air injection.
