Effects of multi-charge on aerosol hygroscopicity measurement by a HTDMA [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
The humidified tandem differential mobility analyzer (HTDMA) is widely used to measure the hygroscopic properties of submicron particles. The size-resolved aerosol hygroscopicity κ measured by a HTDMA will be influenced by the contribution of multiply ...
