TEOM® Mass Transducer (1)Tapered element oscillates at its natural frequency (simple harmonic oscillator).Particulate matter collects on filter continuously.Frequency decreases with accumulation of mass.Direct relationship between mass and frequency change:

Tapered element physical characteristics (material, configuration, housing) chosen so mass sensor calibration constant (K0) has insignificant response to temperature. (For example, the change in K0 for a TEOM monitor operating at 30 °C and 50 °C is less than 1%.)

Tapered Element

TEOM® Mass Transducer (2)

Equation describing tapered element is derived from physical law. Not an approximation. Approach similar to laboratory microbalance in that mass detected by sensor is result of measurement of change in fundamental physical parameter (e.g., frequency, strain, displacement)

Tapered element typically kept in constant elevated temperature (user-selectable) environment to

Minimize water interference from both sample air- moisture content and particle-associated water

Provide high stability for real-time measurementTapered Element

Applications of Continuous PM Monitors

Provide continuous daily integrated “FRM”-like measurements

Provide representative one-hour PM measurements for public reporting (air quality index, mapping, forecasting) and health effects studies

Reduce labor and other costs associated with manual sampling methodologies

22

Where Does This Lead?

Challenge: identify continuous PM monitoring method that provides “FRM”-like integrated results that can be used for regulatory purposes while providing meaningful, high-precision short-term (i.e., hourly) data

Requires blending of regulatory and scientific needs

23

Forward Looking Statement

R&P is committed to solving PM measurement issues to enable continuous monitoring in areas containing particulate nitrate and volatile organic compounds

Instrumentation is based on first principles to provide calibration based on scientific considerations (not empirically-derived calibration factors) for universal measurement consistency from site to site
