| Description | Ion Source 内に搭載され、サンプル試料の分子をイオン化するためにフィラメントから熱電子を放出します。 |
- The gas sample passes through an electron impact ion source, which operates under vacuum.
Positive ions form when electrons, accelerated from a thermionic filament, bombard the sample molecules and cause the loss of one or more electrons.
The process of ionization is often sufficiently energetic to rupture chemical bonds, so that fragment ions are formed as well as molecular ions.
