| Zusammenfassung: | The invention relates to a device for mass selective determination of at least one ion or of a plurality of ions. The device according to the invention is used for example in a measuring apparatus having an ion trap (1404). The ion trap (1404) has a ring electrode (1401) having a first opening. A first electrode (1402) is arranged at the first opening. Furthermore, an amplifier (1408) for providing a radio-frequency storage signal for the ion trap (1404) and a first transformer (1411) are provided, said first transformer being connected to the amplifier (1408) and the first electrode (1402) in such a way that the radio-frequency storage signal is coupled into the first electrode (1402) via the first transformer (1411). |
