Email: info@standard-groups.com
The Humidified Tandem Differential Mobility Analyzer (DMA) system has two differential mobility analyzers and a humidification section in between. Aerosol from the ambient atmosphere or from the built-in aerosol generator can be classified by the first DMA to produce a monodisperse aerosol for size analysis by the second DMA to determine the growth in particle size as a function of relative humidity.
