FIELD: mass-spectrometry. SUBSTANCE: during period of high-frequency voltage applied to analyzer electrodes, like-polarity pulse voltages spaced in time are successively applied at least once. Analyzer electrodes are placed at same potential during time space between these pulses. EFFECT: improved sensitivity of analyzer due to changing shape of amplitude-frequency response, improved resolution and sensitivity of hyperboloid mass-spectrometer. 1 dwg
