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.

Particulate Matter Emissions
TSI DustTrak DRX and DustTrak II
Portable light-scattering laser photometer that monitors real-time aerosol mass readings. It simultaneously measure size-segregated mass fraction concentrations corresponding to PM1, PM2.5, respirable, PM10 and PM Total size fractions.
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.
TSI AERODYNAMIC PARTICLE SIZER (APS)
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.
Gravimetric PM Sampling Train and Analysis
Measures gravimetric PM or PM2.5 and volatiles (optional). Filters are weighed with a 0.0001 mg resolution ultra-microbalance.
