It uses two Differential Mobility Analysers (DMAs), operated in series. The incoming air sample is dried to <10% relative humidity, and the first DMA selects a monodisperse distribution of a chosen size. The monodisperse subsample is humidified, and the second DMA, coupled to a particle counter, measures the size distribution of the humidified sample."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL0352" ; skos:note "accepted"@en ; skos:prefLabel "Manchester Centre for Atmospheric Science Hygroscopic Tandem Differential Mobility Analyser"@en ; skos:related .
