Original Abstract

A gerdien tube (GT) is instrumental towards the measurement of air ions concentration assuming that the volume of tested air has not been limited and the ions are continuously generated. In the time domain, it is possible to measure only ions of one polarity by means of a gerdien tube; then, following a certain interval, ions of the other polarity can be measured. Ionized air is sucked into the gerdien tube by a fan. A homogeneous electric field is set between the inner and the outer electrode. If an electric ion shows a negative electric charge and the collecting inner electrode has a positive electric potential, the ion is progressively attracted to the inner electrode. Provided that the ion impinges upon the electrode, it will induce an electric current that is measured by the help of a sensitive electrometric picoampermeter. The velocity of the ions motion in the electric field can be described by mobility k [ m2*V-1*s-1].
