Abstract: Clean corona gas ionization by separating contaminant byproducts from corona generated ions includes establishing a non-ionized gas stream having a pressure and flowing in a downstream direction, establishing a plasma region of ions and contaminant byproducts in which the pressure is sufficiently lower than the pressure of the non-ionized gas stream to prevent at least a substantial portion of the byproducts from migrating into the non-ionized gas stream, and applying an electric field to the plasma region sufficient to induce at least a substantial portion of the ions to migrate into the non-ionized gas stream.

Abstract: A particle sensor comprises an electrostatic particle charging section and a parallel-plate particle precipitation section, and a sensor for detecting the precipitated particles to produce a sensor signal. A pre-filter is placed upstream from the particle charging section. The pre-filter characteristics are such that the sensor signal in response to entrained particles which are not filtered out by the pre-filter relates to the apparent particle number concentration Napp of the particles entering the particle sensor by a calibration constant S which is less dependent on the count mean particle diameter dp,av of the particles entering the particle sensor than the dependence on dp,av that exists in the absence of the pre-filter. Thus, the dependency of the sensor signal derived from the particle deposition in the parallel-plate precipitation section on the particle size distribution (caused by incomplete particle deposition in the precipitation section) is at least partly compensated for by a pre-filter which has a suitable dependency of its filtering function on the particle size.
