Abstract
The present invention provides a small-sized ion detecting device that quickly and simply performs mass analysis under atmospheric pressure. Accordingly, electrodes are arranged and held in the ion detecting device so as to be able to detect water clusters in ambient air with a high sensitivity. Thereby, ions can be detected even in a spatially-restricted place.
