Abstract
In a mass spectrometer provided with a measurement section () including a collision cell () and a mass separator (-) for a mass spectrometric analysis of product ions, a CES-method-condition determiner () determines collision-energy (CE) values for a collision energy spread (CES) method according to given conditions including the range and number of CE values, in such a manner that n+1 CE values to be used when the number is n+1 (where n is an integer equal to or greater than three) include n collision-energy values used when the number is n and one additional CE value different from the n CE values. An analysis controller () sequentially changes the collision energy to the n+1 CE values and controls the measurement section to execute an MS/MS analysis under each CE value. A data processor () obtains a cumulative mass spectrum by accumulating mass spectra respectively obtained under different CE values.
