Mobile Air Monitoring

Real-Time Mobile Monitoring of Ambient Air VOCs

Background

Ambient Air Mobile Monitoring

Ambient air contains a dynamic and diverse mixture of volatile organic compounds (VOCs). The concentration and composition of this VOC mixture, and its variation with location and time, provide vital insight to emission sources and chemistry. Vehicles equipped with fast, sensitive instrumentation let VOC science move out of the laboratory and into the real world.

Because of its small size, low power requirements, robust construction, and ability to directly measure ambient air multiple times a second, TOFWERK instrumentation is ideal for measurement from aircraft, cars, and other mobile platforms. Using a “mobile” laboratory equipped with a TOFWERK Vocus PTR-TOF, researchers can achieve a detailed and comprehensive picture of the ambient environment by tracking emission sources, quantifying and characterizing their VOC signatures, and following pollutants as they are transported downwind.

Solutions
