The Tandem Differential Mobility Analyzer (TDMA) is an in situ airborne and ground-based analyzer that measures the physical properties of aerosol particles such as size distribution and concentration. It can measure particles in the size range of 0.013 to 0.75 mm at a size resolution of 0.013 mm at 0.2 mm. The TDMA is sometimes combined with an Aerodynamic Particle Sizer (APS) to allow measurements of particles in the submicron range. A typical measurement sequence of TDMA can take approximately 45 minutes to complete.
