Application of the soft X-ray TSI Advanced Aerosol Neutralizer to aerosol measurements made by a Grimm SMPS

Scanning Mobility Particle Sizer (SMPS) spectrometers are subject to several restrictions when radioactive sources are employed to bring the aerosol to a steady state charge distribution. An alternative solution is represented by neutralizers based on soft X-rays. The present research investigates, for the first time, the outcome of a combination of the soft X-ray advanced aerosol neutralizer (TSI model 3087) with a Grimm SMPS (L-DMA, mod. 5400).
