Abstract
The invention relates to the voltage supply of mass spectrometers, particularly electrostatic Kingdon ion analyzers, requiring extremely noise-free operating voltages. The invention proposes the use of passive charge storage devices, which operate without any feedback control and display no measurable noise or ripple if they are well shielded, instead of the usual actively operating high-voltage generators. Chemical charge storage devices or capacitors with good insulation can be used for this purpose. These may display slight voltage decreases due to continuous discharge, depending on their quality, but these decreases can be mathematically compensated.
