Abstract

A novel thermophoretic sampling device for probing nanoparticle aggregates in all types of flames as well as in particle-laden gases and aerosols is presented. For the motion of the sampling probe, a tubular electric linear motor is utilized, and its design and operation are described in detail. The spatial and temporal performance is determined from oscilloscope measurements and high-speed recordings of one motion profile featuring three different resident times. Motion sequences offering a minimum residence time of 3 ms and a maximum velocity of 4.1 m s
