The electronic unit of a conventional dual-collector mass spectrometer is modified so as to measure relative ion currents even when their mass difference is considerably large. In the present device, two square-wave voltage pulses are successively impressed on the ion source to accelerate ion beams alternatively and collect them on each collector, and after amplified respectively by a. c. amplifier their outputs are balanced out by means of precision attenuators, which may then indicate the ratio of the two ion currents immediately. The essential circuit diagrams and experimental results are given which show the device to be useful for industrial purposes.
