Mass spectrometer

摘要

A sample separated through a pre-processor part 1 having a gas chromatography (GC) or liquid chromatography (LC) and a moving-bed eliminating part 2 is ionized by an ion source 3 and mass-analyzed by a mass-analyzing part 4. The mass-analyzed ions are deflected and focused by a deflecting portion A and a focusing portion B in a deflecting and focusing part 5, and detected by an ion detecting part 8. The result of detection is processed by a data processing part 11. <IMAGE>
