Abstract
A mass spectrometer system for performing a separation of ions from neutrals and mass analyzing ions comprising a inductively coupled plasma ion generating source with an ion introducing system, a radio-frequently ion guide and a mass analyzer disposed within a vacuum chamber. The space between the radio-frequency ion guide and the ion introduction system defined an aerodynamic jet region which is used for directing a sample containing ions to be analyzed to the entrance of a radio-frequency ion guide and the via the radio-frequency ion guide to the mass analyzer.
