A mass spectrometer and method capable of optimizing the opening time of a collision cell includes: an ion source (10) for ionizing a sample; a first mass analyzer (30) for selecting first desired ions from the ions generated in the ion source (10); a collision cell (40) for fragmenting some or all of the first desired ions into product ions; a second mass analyzer (50) for selecting second desired ions from the first desired ions and the product ions; a detector (60) for detecting the second desired ions; and a control section (200) for controlling the collision cell (40) in such a way that the cell performs a storing operation for storing the first desired ions and the product ions for a given storage time and then performs an opening operation for ejecting the stored ions for a given opening time based on information about settings in an adjustment mode. |
