Abstract

In order to improve the accuracy of deterioration determination, an ion source system (10) comprises an ion source (100) and a control device (400), wherein: the ion source (100) includes a capillary (121) that sprays a sample solution (Q), a counter electrode (131) that generates an electric field for ion generation between the capillary (121) and the counter electrode (131), and a correction electrode (110) that is disposed in a space in which the capillary (121) and the counter electrode (131) are installed; and the control device (400) determines the presence or absence of deterioration in the capillary (121), the counter electrode (131), and the correction electrode (110) on the basis of a change in a first graph and a change in a second graph.
