The APM consists of two cylinders rotating at a rotational speed, ω. The aerosol is introduced in the gap between the cylinders and a radial electrical field is applied. The electrical force keeps the charged particles in orbit. The mass distribution of the particles is measured by stepping the APM voltage (V APM) at a specific ω.
