Abstract

As the first part of a thorough investigation of spray-produced ions, we have measured their mobility under varying conditions of age, humidity and composition of the sprayed droplets. The most noteworthy result is the low mobility of the final positive ion (about 0.95 × 10-4 m2/Vs) compared to that of the negative ion (about 1.77 × 10-4 m2/Vs). The mass differences which this implies are discussed.

In a supplementary experiment it was shown that as the concentration of NaCl in the sprayed solution increased, so did the density of salt nuclei in the plume of the evaporating spray.
