Product Details

MOUDI™ models 100NR, 100S4, and 110NR are precise cascade impactors with sharp cut-size, low internal-loss characteristics, and high accuracy. Members of the MOUDI family, these MOUDI medium flow rate impactors hold a 30 L/min sampling flow rate.

The medium flow rate impactors are used for collecting size-fractionated particle samples in the 0.056 to 10 µm aerodynamic diameter range for gravimetric and/or chemical analyses. The various MOUDI models hold various number of stages: the Model 100NR has eight impaction stages and cut-size diameters from 0.18 µm to 18 µm. The Model 110NR has 10 impaction stages and cut-size diameters from 0.056 µm to 18 µm. The Model 100S4 has three impaction stages with cut-size diameters of 1.0, 2.5 and 10 µm. Particle deposits are collected on standard 47-mm substrates which can be analyzed for mass, or via chemical analysis or microscopy.

Features & Benefits:

  • Sharp cut-off size characteristics
  • 30 L/min sampling flow rate
  • Micro-orifice nozzle plates designed for low flow resistance and reduced particle bouce and re-entrainment
  • Up to 10 impactor stages with nominal cut points between 56 nm and 10 µm, plus a final filter
  • Low inter-stage losses
  • Easily removable collection substrates allow for quick turn-around time for productive use of the instrument
  • Made of hard-coated anodized aluminum for light weight, durability and nozzle dimensional stability

Applications:

  • Sampling of atmospheric aerosols for research and environmental monitoring
  • Workplace aerosol analysis
  • Engine emissions analysis and monitoring
  • Brakewear analysis
  • Exposure monitoring
  • Industrial hygiene studies
  • Tobacco smoke and e-cigarette characterization
  • Biological aerosol characterization
