Particle concentrator |
摘要 |
Particles in a fluid flow are concentrated by a combination of electrical charging and focussing and passage through a virtual impact concentrator. The fluid is passed through an electrical charging section and an electrical focussing section and then to a virtual impact concentrator. The majority of charged particles in a selected size range are collected through a minor discharge passage extending axially from the virtual impact concentrator. The invention is particularly suitable for sampling engine exhaust gases and ambient aerosols.
