摘要： PROBLEM TO BE SOLVED: To increase the reliability of an analyzed result using a capillary electrophoretic mass spectrometer by a method wherein a plurality of analytical operations are performed under the same analytical condition, the electrophoretic times of at least one substance are compared and the time base of the obtained analyzed result is corrected. SOLUTION: Ion electropherograms obtained, in a first analytical operation and a second analytical operation, of ions whose value m/z obtained by dividing the valence of ions by the molecular weight of ions is (x) are designated respectively as A and B. A peak caused by the ions to which attention is to be paid is designated as P1 , the peak P1 is observed at a time t1 in the electropherogram A, and it is observed at a time t1 in the electropherogram B. When the time base of the electropherogram B is corrected by making use of the peak P1 in the electropherogram A as a reference, the peak P1 in the electropherogram B is observed at the time t1 ' although it should be observed at the time t1 . As a result, the time base in the electropherogram B is multiplied by t1 /t1 ' so as to obtain a time base after it has been corrected in the electropherogram B. Thereby, an apparent time base in the electropherogram A agrees with that in the eletropherogram B, and the elecropherograms A, B can be compared directly.

CONSTITUTION: Insulating materials 11a, 11b are inserted between two end cap electrodes 14a, 14b and one ring electrode 15 of an ion trap mass analysis part to turn the mass analysis part into a sufficiently closed space. Helium gas is directly introduced to the insulating material part via a piping from a helium gas feed source 28 which is outside the vacuum space. The ion trap- type mass spectrometer is characterized as above.
