TSI 140 QCM-MOUDI Real-time Quartz Crystal Microbalance Impactor

Description of TSI 140

A breakthrough in cascade impactor technology for size-fractionation and mass measurement of aerosols, MSP’s MOUDI™ Impactor is now available with Quartz Crystal Microbalances (QCMs) for real-time mass measurement.

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.
