·Manufacturer: Aerodyne Inc.
·Location: Lash Miller. MAPLE
The AMS is a non-intrusive instrument capable of measuring aerosol chemical composition, and can also monitor chemical composition as a function of particle size for particles ranging in size from 50 to 700 nm. Particle time-of-flight measurements are used to determine the size of aerosols, while time-of-flight mass spectrometry is used to determine their composition with a time resolution as high as 1 second.
Proton-Transfer-Reaction Mass Spectrometer (PTR-MS) with fast ion source/drift tube system
·Manufacturer: Ionicon Analytik
·Location: WB facility (Field Measurement). MAPLE
The PTR-MS provides real-time concentration measurements of volatile organic compounds (VOCs) with a detection limit in the parts per trillion range, and an instrument response time of less than 100 milliseconds. The instrument uses a soft ionization method, which involves proton transfer from H3O+ ions to compounds with a higher proton affinity than water, to deduce VOC concentration. This method eliminates interference from common gases found in air such as N2, O2, and CO2.

Scanning Mobility Particle Sizer (SMPS) Model 3080
The SMPS measures aerosol concentration as a function of particle size using bipolar charge distribution and differential mobility analysis methods. This fast-scanning instrument allows for measurements to be taken at a 60-second time resolution. The SMPS Model 3080 also provides the option to vary the differential mobility analyzer (DMA) depending on target size measurements. A long DMA (model 3081) can be used to measure particles of a broad range from 10 to 1000 nm, or alternatively, a nano DMA (model 3085) can be used to more precisely classify particles from 2 to150 nm.
