A high transmission axial ion mobility classifier for mass-mobility measurements of atmospheric ions [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Abstract. We present an electrical mobility classifier for mass-mobility measurements of atmospheric ions. Size segregation coupled with mass spectrometric detection of naturally occurring ions in the atmosphere is challenging due to the low ion concentration.
