Abstract
A servoamplifier combined with a compensatory circuit is presented, permitting the measurement of ion current ratios in the range 1/106-1/200 in a two collector mass spectrometer with an accuracy to 002%. By means of this automatic method the measurement and continuous recording of the isotopic abundance variation in dynamic conditions can be carried out.
