Mass spectrometry system having ion deflector

摘要

A tandem mass spectrometer and method for calibrating a tandem mass spectrometer. The tandem mass spectrometer comprises first and second mass analyzers. The first and second mass analyzers form an ion path. The second mass analyzer is positioned downstream from the first mass analyzer and is arranged to receive ions from the first mass analyzer. An electrode arrangement positioned between the first and second mass analyzers. The electrode assembly is configured to selectively deflect ions from the ion path.
