The Tandem Differential Mobility Analyzer (TDMA) is an in situ airborne and ground-based analyzer that measures aerosol particle properties, including size distribution and concentration. It measures particles in the size range of 0.013 to 0.75 mm, with a size resolution of 0.013 mm at 0.2 mm. The TDMA is often combined with an Aerodynamic Particle Sizer (APS) to enable measurements of submicron particles. A typical TDMA measurement sequence takes approximately 45 minutes to complete.
