  • Wind direction-based air sampling
    Patent number: 10119890
    Abstract: Methods, apparatuses, and systems for air sampling and emissions monitoring based on wind direction, including determining concentrations of air toxics, are contemplated. Some embodiments comprise detecting wind flowing in a first direction and a second direction, exposing a sample collection device to air in response to detecting the first direction and preventing exposure of the sample collection device to air in response to the second direction. Some apparatuses comprise a direction detector, an enclosure, and a sample preventer. Some embodiments comprise a purger configured to purge the sample collection device when preventing exposure of the sample collection device to air. In some embodiments, the sample collection device comprises a diffusive sorbent tube. In some embodiments, the diffusive sorbent tube is configured to collect samples of benzene. Some embodiments comprise a wind vane and sensor configured to provide indication of wind direction. Some embodiments comprise a data collector.
