Research Facilities

About the Stoves Lab

Our research facility is located at Lawrence Berkeley National Lab in Berkeley, California, close to the UC Berkeley campus. The facility is outfitted with several instruments to measure emissions and performance of wood burning technologies. We are also equipped to conduct standardized tests (e.g., ISO, ASTM, EPA, etc.) for supporting research and development of novel wood burning technologies. Data collected can be used to advance technologies, quantify impact on environment and health, validate sensors, and inform policy.

TSI Fast Mobility Particle Sizer (FMPS) 3091

Measures particle concentration and size distribution from 5.6 to 560 nm with 1 Hz time resolution.

TSI Optical Particle Sizer (OPS) 3330

Portable measurement of particle concentration and size distribution from 0.3 to 10 micrometers with a sampling rate of 1 Hz.


Measures concentration and size distribution of particles with aerodynamic diameters from 0.5 to 20 micrometers and with optical diameters from 0.3 to 20 micrometers.

Magee Scientific AE22 Black Carbon (BC) Aethalometer

The aethalometer collects particles on a filter and measures the attenuation of 370 and 880 nm light through the filter. Black carbon (BC) concentration is determined from the measurement at 880 nm and a stove-smoke-specific calibration was developed for the BC aethalometer measurements. The results were compared with particle light-absorption coefficients measured with a photoacoustic absorption spectrometer (PAS) and elemental carbon concentrations measured using a thermal–optical analysis method. The measurement at 370 nm indicates the presence of light absorbing organic compounds in wood smoke in addition to BC. The aethalometer has a sampling rate of 0.2 Hz.
