Abstract
A rotating field mass spectrometer includes an ionizing structure having a pair of conductive electrodes located closer to one another than the mean free path of the gas being ionized, and a rotating field mass spectrometer part for analyzing ions produced by the ionizing structure. The membrane may include a supporting portion, and a relatively thin non-supporting portion where the ions are formed.
