MOUDI impactors are classic, precise cascade impactors with sharp cut-size, low internal-loss characteristics, and high accuracy. These cascade impactors provide sharp cut-sizes, low internal losses, and high accuracy in a non-rotating configuration with a 30 L/min smapling flow rate.
The MOUDI impactors, 100NR, 100S4, and 110NR, 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, as listed in the table below, the classic MOUDI’s hold various impaction stages and cut-sizes. Particle deposits are collected on standard 47-mm substrates which can be analyzed for mass, or via chemical analysis or microscopy.
| Model | Stages | Nominal Cut Points (µm) @ 30 L.min inlet flow rate | Pressure Drop (kPa) |
|---|---|---|---|
| 100S4 | 3 | 10, 2.5 and 1 | 1 |
| 100NR | 8 | 10, 5.6, 3.2, 1.8, 1.0, 0.56, 0.32. and 0.18 | 10 |
| 110NR | 10 | 10, 5.6, 3.2, 1.8, 1.0, 0.56, 0.32, 0.18, 0.10, and 0.056 | 40 |
