Abstract

PURPOSE:To enable the detection of meta-stable ions of particular ions, by scanning the intensity of magnetic field while scanning the electric field voltage when said intensity will reach the level corresponding to the peak of the mass number of the ion to be detected. CONSTITUTION:The component of the specimen analyzed by a gas chromatograph 1 will enter through an ion source 2 into an electric field 5 to be focused into a slit 6, then enters into a magnetic field 7 and detected by a collector 9. The electric field 5 and the magnetic field 7 are connected through D/A converters 11, 14 to an operation control section 12 to operate the magnetic field with predetermined period, and when the intensity of the magnetic field will reach the peak level of different mass number of every scan the voltage of the electric field 5 is operated. Consequently the meta-stable ion for the peak of mass number of ion having different mass number in time sharing can be obtained simultaneously within the period where the component material is resolved from the separated column.
