PURPOSE:To easily establish switching between common mass analysis and analysis of ion split reaction caused by collision activation by slidably moving an integrally coupled ion source slit and collision chamber in the direction crossing with the ion track. CONSTITUTION:A double convergence mass analyzer capable of analyzing ion split reaction caused by collision activation by a linked scan method is formed so that an integrally coupled collision chamber CC and ion source slit Si can be slidably moved in the arrow mark A direction, perpendicular to an ion track O. For an ordinary mass analysis, the ion source slit Si is positioned on the track, and on the other hand, for the analysis utilizing the linked scan method of ion split caused by collision activation, the slit Si is withdrawn to position the collision chamber CC on the ion track. Thereby, contamination of the colli sion chamber can be prevented and a process for positioning it can also be omitted. |
