Abstract
A collecting device for collecting particles floating in the atmosphere includes a collecting container; a pump for sucking the atmosphere into the collecting container; a discharge electrode disposed in the collecting container for generating single polarity ions to charge the particles in the collecting container; and a dust-collecting electrode for collecting the charged particles in the collecting container through a potential difference between the discharge electrode and the dust-collecting electrode. The dust on the dust-collecting electrode is measured and analyzed.
