A tapered element oscillating microbalance (TEOM) is an instrument used for real-time detection of aerosol particles by measuring their mass concentration. It makes use of a small vibrating glass tube whose oscillation frequency changes when aerosol particles are deposited on …

Take continuous direct mass measurements of particulates using a tapered element oscillating microbalance (TEOM) with the Thermo Scientific™ 1405 TEOM™ Continuous Ambient Particulate Monitor. This monitor measures TSP, PM-10, PM-2.5, and PM-1 airborne particulates with excellent short term precision.

Particulate matter monitoring systems that employ tapered element oscillating microbalances (TEOM) technology are “gravimetric” instruments that draw (then heat) ambient air through a filter at a constant flow rate, continuously weighing the filter and calculating near real-time mass concentrations of particulate matter.

Simultaneously measure PM Fine (PM-2.5), PM Coarse, and PM-10 mass concentrations with the Thermo Scientific™ TEOM™ 1405-D Continuous Ambient Particulate Monitor. This monitor utilizes a tapered element oscillating microbalance (TEOM) for measurements with excellent short-term precision.

Tapered element oscillating microbalance (TEOM) is a technique used to continuously measure concentrations of air particles. It consists of an instrument fitted with a size-selective inlet to sample one of the following particle size ranges: total suspended particulate (TSP) particles less than 10 micrometres in diameter (PM 10)

Element Oscillating Microbalance, or TEOM®) in near real time. Both of these methods use the Filter Dynamic Measurement System (FDMS®) to estimate and adjust for the volatile component of the mass. These two methods (monitors) are very similar, with the main difference being that

The TEOM 1400ab monitor is used to monitor ambient air quality in the following major applications: • Air quality monitoring networks, including background sites • Special studies and supersites • Routine input for air quality index • In and around industrial and material handling facilities • Remediation projects

The acronym TEOM stands for “Tapered Element Oscillating Microbalance,” an inertial measurement technique that operates on changes in the resonant frequency of an oscillating element as a function of increases in particle mass collected on a filter attached to the element.

The Rupprecht and Patashnick Tapered Element Oscillating MicroBalance (TEOM) method for PM is compared with time-integrated gravimetric (manual) PM methods in large urban areas during different seasons.

This monitor utilizes a tapered element oscillating microbalance (TEOM) and Filter Dynamics Measurement System (FDMS) to provide measurements with excellent short-term precision and account for volatile and nonvolatile PM fractions.
