    • PROBLEM TO BE SOLVED: To provide a tandem time-of-flight mass spectrometer accompanied with attenuation in a collision chamber, and its using method. SOLUTION: In the tandem mass spectrometer, an effective coupling of a first time-of fight mass spectrometer to a second mass spectrometer of any one of various types, including a time-of-flight mass spectrometer with orthogonal acceleration, through use of a collision chamber with collisional attenuation is provided. The generally preferred tandem mass spectrometer is equipped with the followings. A pulse generator of ions coupled to the time-of-flight mass spectrometer, a time-limited ion selector, the collision chamber with a gas of sufficiently high pressure to attenuate by collision the admitted ion beams and to induce fragmentation in communication with the time-of-flight mass spectrometer and the time-limited ion selector, and the second mass spectrometer to analyze fragment ions.
