Abstract: PROBLEM TO BE SOLVED: To realize a mass spectrometric method in which the condition of a cleavage reaction can be judged automatically by one sample injection, whose operability is enhanced and in which the condition can be adjusted in a short time. SOLUTION: In step S1, a sample is injected. In step S2, a cleavage condition 1 is set. In step S3, ions are generated. In step S4, a spectrum in a mass number range of 100 to 800 is obtained. In step S5, when an ion intensity is at a threshold or higher, the ions in a mass number whose ion strength is the highest are selected in step S6. In step S7, a cleavage reaction is performed under a cleavage condition X. In step S8, a mass spectrum under the condition X is acquired so as to be stored in a memory in step S9. In step S10, the cleavage condition is changed. In step S11, whether a set time has elapsed or not is judged. When the time has not elapsed, this procedure is returned to step S3.  When the set time has elapsed in step S11, a cleavage condition in which the ratio of the generated ion strength to the selected ion strength is the highest is judged in step S12 on the basis of spectrum data which is stored in the memory.
