Assistant Director of User Services for FAB.nano Jorg Scholvin demonstrates the portable particle counter (readings below are 0.5um particles and larger) in four quick experiments, which show how strong an influence user activity and behavior has on the particular contamination that reaches a sample:
1. Holding hand above inlet: 39 particles
2. Tugging on sleeve exposing skin (photo): 1779 particles
3. Counting from 1 to 20 with face above inlet, with face cover: 11 particles
4. Counting from 1 to 20 with face above inlet, without face cover: 155 particles
