MOUDI-II Impactors 120R, 122R, 125R

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 models 120 and 122, 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 122 and 125 (see table below).

Applications

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

Features and Benefits

• 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
