Abstract
An MT-TOFMS which is one mode of the present invention includes: a linear ion trap (2) configured to temporarily hold ions to be analyzed, and to eject the ions through an ion ejection opening (211) having a shape elongated in one direction; a loop flight section (3) configured to form a loop path (P) capable of making ions repeatedly fly; and a slit part (5) located on an ion path in which the ions ejected from the linear ion trap (2) travel until the ions are introduced into the loop path, the slit part configured to block a portion of the ions in a longitudinal direction of the ion ejection opening (211).
Claims3
A multi-turn time-of-flight mass spectrometer, comprising:
- a linear ion trap configured to temporarily hold ions to be analyzed, and to eject the ions through an ion ejection opening having a shape elongated in one direction;
- a loop flight section configured to form a loop path capable of making ions repeatedly fly;
- and
- a slit part located on an ion path in which the ions ejected from the linear ion trap travel until the ions are introduced into the loop path, the slit part having an ion passage opening whose length in the one direction is shorter than a length of the ion ejection opening in the one direction and configured to block a portion of the ions in the one direction of the ion ejection opening.
