Compared to more traditional cascade impactor designs, the Quartz Crystal Microbalance (QCM) MOUDI™ Impactor has taken setup and measurement time from hours to minutes. The excellent mass measurement accuracy of the QCM MOUDI™ impactor is ensured by the integrated humidity conditioning system. This humidity conditioning system promotes reliable coupling of aerosol particles to the quartz crystal sensors, and eliminates undesirable solid particle bounce. Sampled masses on each stage can range from tens of nanograms up to a few hundred micrograms. The QCM MOUDI™ has an inlet that removes particles larger than 2.5 micrometers, and a sample flow rate of 10 L/min.
