Cascade Impactors

MOUDI-II and NanoMOUDI-II impactors are second generation Micro-Orifice, Uniform-Deposit Impactors from MSP. These impactors are noted for their superior aerodynamic design, sharp cut-size, and low particle loss characteristics. Up to 6000 precision micro-orifice nozzles are used to reduce pressure drop, jet velocity, particle bounce, and re-entrainment.
