Title:
HYBRID ION SOURCE, MASS SPECTROMETER, AND ION MOBILITY DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/084015
Kind Code:
A1
Abstract:
The present invention provides an ion source which exhibits high sensitivity and high robustness even when a plurality of ionization systems is carried out at the same time. This hybrid ion source (1) is configured of a chamber (24), a first ion source (2) which atomizes and ionizes a sample solution (5), a second ion source (3) which ionizes the droplets and/or gas component atomized by the first ion source (2), a first electrode (11) into which first ions (7) formed by the first ion source (2) and second ions formed by the second ion source (3) are introduced, and an evacuation pump (27) which generates a gas stream (26) flowing from the first space region (23) where the first ions (7) are formed toward the second space region (19) inside the second ion source (3) where the second ions are formed.
