ROTATING IMPACTORS: MOUDI-II IMPACTORS 120R, 122R, 125R

For more than a decade, MOUDI-II™ Impactors have enabled researchers to push their research further than was possible with the original MOUDI design. With internally-mounted motors to rotate the impaction plates, MOUDI-II impactors can now be used reliably for longer sampling intervals (i.e. days). Characterizing airborne particulate matter in terms of its mass and/or chemical content provides insight into ambient air quality, atmospheric science, vehicle emissions, industrial emissions, and other areas. Stage cutpoints down to 10 nm allow researchers to study particle composition at the nanoparticle level, confident that their results are not tainted by larger particles from a different source.

MOUDI-II impactors are based on the legacy and research quality of the preceding MOUDI impactors by MSP. They are now sold by TSI, making them part of a large family of trusted, accurate, and reliable aerosol instrumentation

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).
