Abstract
PURPOSE: To make possible setting of acceleration voltage through one sample injection by superposing a sweep signal on the acceleration voltage which accelerates the ionized sample and integrating the detection signals at each level of the acceleration voltage by way of a computer.
CONSTITUTION: The sample having been ionized in an ion source 1 is accelerated by the superposed voltage of the acceleration voltage from a reference power source 9 changing stepwise and the sweep voltage from a sweep circuit 12 through a changeover circuit 10 controlled by a computer 7 and is then detected in an ion collector 4 through a fixed intensity analyzing magnetic field 3. The detected values thereof are integrated in the computer 7 by way of an A-D converter 6 and the integrated value by each acceleration voltage is individually stored in a memory 8. From the integrated value corresponding to the distribution of the ions according to this acceleration voltage, the acceleration set voltage for concentrating the peaks of the ion beams in the collector 4 is set through one sample injection without making intricate adjustments, thus the mass spectrometric analysis may be performed readily, accurately and rapidly.
