ABSTRACT:
Ions generated by an ES ion supply are introduced into a mass spectrometer portion through a small hole in a second electrode after passing through a small hole in a heated first electrode, and are analyzed by a mass spectrometer. Corresponding to heating of the first electrode, a length of the small hole in the first electrode is determined to a predetermined adequate value.
