Product Details

The QCM MOUDI is a precision research-grade impactor with real-time mass detection based on QCM (Quartz Crystal Microbalance) sensors. The impactor has a 2.5-µm inlet and six QCM stages with sharp collection efficiency curves and calibrated cutpoints of 960, 510, 305, 156, 74 and 45 nm at 10-L/min inlet flow rate. The QCM MOUDI provides excellent mass measurement accuracy thanks to the integrated humidity conditioning system that ensures reliable coupling of aerosol particles to the quartz crystal sensors, and eliminates undesirable solid particle bounce. With the QCM MOUDI, setup and measurement time has gone from hours to minutes allowing the user to collect size fractionated aerosol masses, in real time (1 Hz data collection), from tens of nanograms up to a few hundred micrograms.
