ABSTRACT:
Particulate collector is carried onto airplane and collects suspended particulate matter in the atmospheric air in such a manner that suspended particulate matter is electrically charged by single-pole ions generated by a discharge electrode and the thus electrically charged particulates are attracted to a collecting electrode having an electric potential difference with respect to the discharge electrode so that the particulates are collected by the collecting electrode. The particulate collector is conveyed to an arbitrary altitude and driven so as to collect suspended particulate matter contained in the atmospheric air at the arbitrary altitude. Particulate collector is recovered onto the ground so as to make various measurements or the thus collected particulate collector is subjected to various measurements on airplane.
