Description
Product Details
Individual stepper motors in the Moudi-II impactors provide reliable long-term, internal impaction plate rotation to spread out the particles so they collect in a nearly uniform deposit (ideal for some types of chemical analysis). Sampling flow rates are 30 L/min for the model 120, and 10 L/min for the model 125. These impactors are designed to collect size-fractionated particle samples in four equal geometrical intervals per decade of particle size for mass or chemical analyses. The nominal cut-size diameters for these impactors start a 10 mm and end at 56 nm for the 120, and at 10 nm for the 125.
Features
- 30 L/min or 10 L/min sampling flow rate
- Sharp cut-off size characteristics
- Reliable internal impaction plate rotation provides nearly uniform particle deposits for better quantitative chemical analysis
- Micro-orifice nozzle plates designed for low flow resistance and reduced particle bouce and re-entrainment
- Up to 13 impactor stages with nominal cut points between 10 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
- Programmable logic controller (PLC) controls instrument operation including start and stop times
- Instrument temperature and pressures are measured, recorded, and stored at pre-determined time intervals
- Pump control (ON/OFF)
- Remote operation capability via Ethernet
- Made of hard coated anodized aluminum for light weight, durability and nozzle dimensional stability
