Abstract
PURPOSE:To secure yet more analytic information in addition to the conventional MIKES measurement as well as to aim at the identification of samples and the facilitation of molecular structure determination by making polarity of an impressed voltage on a mass spectrograph and an analyzer invertible. CONSTITUTION:Voltage to be impressed between electrodes Ea and Eb of an energy analyzer should be set to such one that makes an ion with energy dependent upon an ion accelerating voltage passable. In this case, if polarity of an ion doing mass spectrometry is positive, voltage is impressed in a direction where Ea comes to positive and Eb to negative, respectively. Thus, when a magnetic field B is swept and output of an ion detector D is recorded, a mass spectrum of both molecular and fragment ions in a sample is securable. Next, in this mass spectrum, MIKES measurement takes place as to one mass ion. At this time, the magnetic field B is set in accord with the ion mass, and voltage to be impressed between these electrodes Ea and Eb is swept between positive and negative by considering voltage dependent upon an ion accelerating voltage as the maximum. With this sweeping, a daughter ionic spectrum of the opposite polarity against the spectrum made by the MIKES measurement is securable.
