Estimation of the Air Ion Mobility Spectrum by means of a Gerdien Tube with a Segmented Inner Electrod

Original language description

Light negative air ions demonstrably exhibit positive influence on the human organism. The concentration of these ions can be effectively used as the integral criterion for the evaluation of air purity, and there also exists a multitude of other applications. The presented aspiration method enables us to establish the concentration of air ions in the atmosphere. In a gerdien tube fitted with a one-piece inner electrode, measurement of the saturation characteristics must be performed to facilitate the determination of the air ion mobility spectrum. The characteristics represent the relation of the measured current through the inner electrode to the polarization voltage. The measurement is time-intensive and sensitive to temporal fluctuations of the air ion concentration during the measurement. For this reason, a gerdien tube of the first type is used; the device comprises a segmented inner electrode, and the air ion mobility spectrum can be estimated (for two polarization voltages) from individual currents of the inner electrode segments. However, due to the overlapping between the functions G that characterize the transmission functions of the individual electrodes, estimation of the air ion spectrum is not an explicit task. The simulation electrostatic field and air flow is shown in this paper.
