TECHNICAL DESCRIPTION
This invention describes a compact FTMS (Fourier Transform Mass Spectrometry) mass spectrometer. The instrument is based on a new type 1.25 Tesla permanent magnet. This device include a turbo-pump with a background pressure of 5.10-9 Torr, a permanent magnet, a cell with an open structure, efficient gas inlet introduction system and data acquisition/treatment software. The mass spectrometer is compact and portable. No cooling fluids are needed, only an ordinary plug is required. This compact FTMS presents a high resolution and a great accuracy in mass determination. Therefore complex mixtures can be quickly analyzed. Ions can be produced by electronic impact, laser ablation or chemical ionization. If needed, different characterization methods can be used such as CID (Collision Induced Dissociation), photo-dissociation, ion-molecule reactions.
