The Tapered Element Oscillating Microbalance (TEOM) provides real time mass
measurement of selected size particles in ambient air samples. This instrument is used
in national and local air monitoring networks to provide continuous data on the mass
concentrations of particulate matter (PM) of 10µm aerodynamic diameter and less
(PM10) or 2.5µm aerodynamic diameter and less (PM2.5) in ground level ambient air.
The procedure described in this document is for the operation of TEOM samplers
reporting data to the NAPS and AENV network.
The operating manual supplied by the instrument manufacturer (R&P part no. 42-003347
& 42-010978) provides detailed installation and operating procedures. Those procedures
are part of this operating method.
