After a first sample injection by a flow injection method, ion intensity of each product ions is measured by varying collision energy at coarse intervals over a wide energy range in a coarse adjustment mode (S1, S2). The integrated strength values of each type of product ions are compared among different levels of collision energy, and if there is any significant difference, the energy level corresponding to the largest integrated intensity value is determined as an approximate value (S3, Y in S4). Subsequently, a narrow energy range centering around the approximate value and a small interval are determined, the mode is switched to a fine adjustment mode, and the intensity of each product ions is measured by varying collision energy as in the case of the coarse adjustment mode. |
