摘要：In this paper, charge distribution of NaCl aerosol particles having a diameter of 54-292 nm has beenobtained using Tandem Differential Mobility Analyser (TDMA) technique. Because of experimental constraints, thestudies were limited to estimation of the negatively charged fraction up to three electronic units. The non- neutralisedcharged fractions for different sizes were compared with that of neutralised NaCl aerosol particles. It was observed that19-21% particles are singly charged, 15-18% particles are doubly charged and 7-13% particles are triply charged. Thecharged fractions for other than singly charged particles were higher for non-neutralised particles as compared to that ofneutralised particles.
