Abstract: In a mass spectrometer, due to impurities accumulated inside a frame, a withstand voltage may decrease, and electric discharge may occur in an ion source, thereby making it impossible to perform normal measurement. Since a result of abnormality measurement due to the electric discharge cannot be distinguished from measurement abnormality caused by clogging of a tube between a pretreatment unit and a needle, there is a problem in that time is required to identify abnormal portions, and a maintenance property is lowered. As a unit for solving the problem, a return current detection unit connected in series between the frame and an ion source power supply that applies a voltage to the needle and a return current detection unit connected in series between the frame and a counter electrode power supply that applies a voltage to a counter electrode are provided.
