Abstract

See full text

A Time-Of-Flight mass analyzer includes a multipole ion guide located in the ion flight path between the ion source and the flight tube of the Time-Of-Flight mass analyzer. The multipole ion guide can be positioned in the ion path between the ion source and the ion pulsing region of the TOF mass analyzer. The multipole ion guide electronics and the ion guide entrance and exit electrostatic lenses are configured to enable trapping or passing through of ions delivered from an atmospheric pressure ion source. The multipole ion guide can be used for ion transmission, trapping and fragmentation, and can reside in one vacuum pumping stage or can extend continuously into more than one vacuum pumping stage.
