Mass spectrometer system and method for transporting and analyzing ions |
摘要 |
A mass spectrometer system for performing a separation of ions from neutrals and mass analyzing ions comprising an ion generating source with an ion introduction system, a radio-frequency ion guide and a mass analyzer disposed within a vacuum chamber. The radio-frequency ion guide is positioned with respect to the ion introduction system so that a main axis of the radio-frequency ion guide is angled toward a central axis of the ion introduction system. The trajectory of the ions is diverted toward the main axis of the radio-frequency ion guide while neutrals continue their flow along the central axis. The ions from the ion introduction system are transported via the radio-frequency ion guide to the mass analyzer.
