Differential Mobility Analyzer (DMA)

Differential Mobility Analyzer (DMA)

Differential Mobility Analyzer (DMA)

Producer: Grimm

A DMA sizes nanoparticles by their mobility in an electric field. Negatively charged particles are attracted by a positive electrode and for a given voltage, only particles of a certain mobility pass through the DMA via an exit slit in the positive electrode. These particles are then counted by a CPC or FCE. By stepping through the voltage from 10,000V to 5V a particle size distribution is obtained. The DMA can also be used to generate monodisperse aerosols if operated with a fixed voltage.
- Particle clasification in range 0,9 - 1100 nm
- Integrated temperature and pressure sensors
- Up to 255 channels depending on different particles mobility

GRIMM DMAs feature the Vienna-Type design (Reischl et al. 1997, Winkelmayr et al. 1990), well known for highest resolution and lowest diffusional losses even for small particles. Vienna-Type DMA offers flexible design with two electrodes of different length to accommodate a variety of experimental needs.
