Instrument

DMA
Differential Mobility Analyzer

The Differential Mobility Analyzer (DMA) is an in situ device that measures particle electrical mobility to determine their size distribution. It mainly measures aerosols between 10 and 1,000 nm in diameter. DMA can be used for airborne, ground-based, and laboratory measurements.
