Aerodyne produces instrumentation for measuring gases or aerosol particles with fast time response and great sensitivity. Our instruments are used in research and monitoring applications on ground and mobile platforms to measure atmospheric pollutants, combustion, and industrial emissions. We produce aerosol and gas phase (for VOCs and VICs) mass spectrometers, laser trace gas detectors (including our new H2 analyzers), particle extinction monitors, NO2 monitors, and a field deployable GC.
