Abstract

PURPOSE:To automate measurement of resolution without requiring any special sample by measuring the resolution only by means of the single peak for the arbitrary number of masses. CONSTITUTION:An ion 3 is scattered by the electric field E at an electrode 4 and the magnetic field H of a magnet 5. It is projected on a collector 6 and detected. For this purpose, the spectral signal obtained in parallel with a sweep 7 is sampled by an A/D converter 11 based on a clock signal 12 and selectively supplied to a peak hole circuit 14 or a comparator 15 through a switching device 13. The sample data N1 corresponding to the sweep is obtained by a counter 18 and the sample data N2 corresponding to the peak width which is contained in a spectral signal is obtained by a counter 19. Besides, V/DELTAV.N1/N2 is obtained from the sweep rate DELTAV/V which is assigned by a regulator 23.
