Abstract

The amplification of secondary-electron multipliers in mass spectrometers is automatically adjusted by generating mass spectra with single ion signals, determining the average value of the peak heights of these single ion signals, and setting the amplification so that the average peak height assumes a desired nominal value. The amplification may be set via the supply voltage of the secondary-electron multiplier and can be increased or decreased by a desired factor using the known characteristic of the secondary-electron multiplier.
