Abstract

PURPOSE:To compensate accurately the magnetic field intensity for peak center by introducing compensating quantity given as a function of the mass number. CONSTITUTION:A secondary ion generated in a sample 1 is accelerated with an accelerating electorde 2, and detected with an ion detector 10 through an electric field 3 and a magnetic field 4. Outputs of a magnetic field detecting circuit 6 and magnetic field value setting device 7 are compared with a magnetic field controller 8 comprising a comparator, and a magnetic field generating circuit 9 controls an exciting current to obtain magnetic fields of each step corresponding to the output. Because the magnetic field is controlled directly by signals which represent the magnetic field, a mechanism for conversion of magnetic field intensity to mass number is needless. An arithmetic processing unit 13 figures out a peak center magnetic field corresponding to the mass number referring to contents of a memory 17 when the mass number is input from an input unit 18 to the memory 16.
