Abstract:
An ion spectrometer was built to measure the mobilities of charged aerosols. Mobilities were measured for particles down to 0.3 microns in diameter. Difficulties were encountered with the smaller particles however, large particles are easily handled. The electrical atl conductivity can strongly influence the atomization. The susceptibility of a liquid to submicron atomization at higher voltages was found to be dependent on electrical conductivity. Charge per drop for a given drop size was found to be constant. Polarity and capillar diameter do not have a strong influence onmization of organic liquids was studied. Particle size at low voltages and low drop frequency was seen to vary as the square root of surface tension. At high voltages low electrical conductivity can strongly influence the atomization. The susceptibility of a liquid to submicron atomization at higher voltages was found to be dependent on electrical conductivity. Charge per drop for a given drop size was found to be constant. Polarity and capillar diameter do not have a strong influence on the atomization process over the ranges investigated. Author
