Abstract
A device for mass selective determination of at least one ion or of a plurality of ions is used, for example, in a measuring apparatus having an ion trap. The ion trap has a ring electrode having a first opening. A first electrode is arranged at the first opening. Furthermore, an amplifier for providing a radio-frequency storage signal for the ion trap and a first transformer are provided, said first transformer being connected to the amplifier and the first electrode in such a way that the radio-frequency storage signal is coupled into the first electrode via the first transformer.
Claims25
A device for mass selective determination of at least one ion, comprising:
- at least one ion trap for storing at least one ion, wherein the ion trap has at least one ring electrode, wherein the ring electrode has at least one first opening, wherein the ion trap has at least one first electrode arranged at the first opening;
- at least one amplifier for providing a radio-frequency storage signal for the ion trap;
- at least one first transformer which is connected to the amplifier and the first electrode in such a way that the radio-frequency storage signal is coupled into the first electrode via the first transformer;
- and
- at least one primary transformer, wherein the primary transformer and the first transformer have an identical transformer core and an identical primary winding, wherein the primary transformer has a first secondary winding, wherein the first transformer has a second secondary winding, which is different from the first secondary winding, and wherein a winding sense of the first secondary winding and a winding sense of the second secondary winding are different.
A measuring apparatus, comprising:
- at least one ion generating unit;
- and
- a device for mass selective determination of at least one ion, the device including:
- at least one ion trap for storing at least one ion, wherein the ion trap has at least one ring electrode, wherein the ring electrode has at least one first opening, wherein the ion trap has at least one first electrode arranged at the first opening;
- at least one amplifier for providing a radio-frequency storage signal for the ion trap;
- at least one first transformer which is connected to the amplifier and the first electrode in such a way that the radio-frequency storage signal is coupled into the first electrode via the first transformer;
- and
- at least one primary transformer, wherein the primary transformer and the first transformer have an identical transformer core and an identical primary winding, wherein the primary transformer has a first secondary winding, wherein the first transformer has a second secondary winding, which is different from the first secondary winding, and wherein a winding sense of the first secondary winding and a winding sense of the second secondary winding are different.
