In a method of mass spectrometry using a spark ion source 2, a larger number of spark discharges is produced than required for the desired exposure of an ion-sensitive layer, such as a photographic plate, for recording mass spectra and only the number of ion pulses required for the exposure, or only a fraction of each ion pulse, is allowed to pass on to the analyser through the diaphragm 20. The unwanted ions are deflected on to the diaphragm 20 by deflection plates 21, 22 and ions are only permitted to pass when a deflection voltage is removed from the plate 22 by a counter 23 or when the deflection voltage is interrupted for a short time during each ion pulse by a control device. Voltage pulses are supplied to the electrodes 4, 5 of the spark source from a storage chain 6 via resistances 7, 8 and diodes 9, 10 and are triggered by ignition pulses from a pulse generator 11 delivered through a discharge tube circuit 12 and a transformer 13. Each spark discharge pulse delivers a counting pulse to the counter 23 via a capacitor 24. The number of discharges used for the exposure is increased step-wise.
