PARALLEL MASS ANALYSIS

摘要

A system and method of mass spectrometry is provided. Ions from an ion so urce are stored in a first ion storage device and in a second ion storage de vice. Ions are ejected from the first ion storage device to a first mass ana lysis device during a first ejection time period, for analysis during a firs t analysis time period. Ions are ejected from the second ion storage device to a second mass analysis device during a second ejection time period. The i on storage devices are connected in series such that an ion transport apertu re of the first ion storage device is in communication with an ion transport aperture of the second ion storage device. The first analysis time period a nd the second ejection time period at least partly overlap.
