摘要： The invention relates to a radio frequency ion guide construction for use in mass spectrometry that minimizes contamination by allowing ions rejected by the RF confinement field to fly through and away from the ion guide electrodes and preventing them from hitting the sensitive electric potential defining surfaces of the ion guide electrodes. At the entrance end of the ion guide, each electrode of the plurality of electrodes has a front end that is forked or that contains a recessed feature facing an interior of the ion guide. For an electrode that is forked, the teeth of the forked end may have different shapes or tapers, and a conductive mesh may be used to cover a gap between the teeth. Similarly, for an electrode that has a recessed feature, a conductive mesh may cover the recessed feature.

摘要： Certain embodiments described herein are directed to rod assemblies such as, for example, quadrupole, hexapole and octupole rod assemblies. In some instances, the rod assemblies include at least one pole comprising an integral fluid path configured to fluidically couple an ion volume formed by the assembly to an outer volume of the assembly to remove fluid within the ion volume to the outer volume while containing ions of a selected mass-to-charge range.

摘要： Provided are a mass analysis device and a mass separation device which are each capable of repeatedly analyzing or extracting a plurality of ion species having different mass-to-charge ratios in a short time with less restriction on the design and performance of the device by problems arising from the principle of operation and with no limitation on the mass-to-charge ratio range that can be dealt with in principle. A mass analysis device (10) is configured from an ion source (1), an ion introduction unit (2), a mass separation unit (3), an ion detection unit (4), and the like. An ion group is introduced into a separation space (5) at a predetermined acceleration voltage as a pulse synchronized with the phase of a one-dimensional high-frequency electric field. In the separation space (5), ions fly by inertia in an incidence direction, and are displaced in a y-direction by force received from the one-dimensional high-frequency electric field that acts in the direction (y-direction) crossing the incidence direction. Ion species having different mass-to-charge ratios from each other are separated by the difference in displacement amount. At this time, the acceleration voltage and the period of the one-dimensional high-frequency electric field are set such that an ion species to be measured is emitted from the separation space (5) after being subjected to the action of the electric field for one period.

摘要： A method of mounting rods in quadrupole, hexapole, octupole, and other multipole geometries is described. First and second dies are used to hold the rods in the required configuration with the plurality of rods extending through each of the two dies. A coupling arrangement is used to separate the first and second dies, and also prevents motion in the plane of the dies. The rods are seated and retained against individual supports and arranged circumferentially about an intended ion beam axis. The supports are desirably fabricated from silicon bonded to a glass substrate, a support for a first rod being electrically isolated from a support for a second adjacent rod.

摘要： A method and apparatus for operating a mass spectrometer system, having a processing section, provides for the application of both an axial field and periodic application of a flush pulse to the processing section. This gives a reproducible output ion signal from the processing section that is very responsive to changes in operating conditions in the processing section. The mass spectrometer system can comprise: a collision/reaction cell having an input and an output; and a set of elongated rods extending between said input and output, said elongated rods spatially arranged. Separate auxiliary electrodes can be provided to generate the axial field. The invention has particular applicability to ICP-MS, where strong ion currents can result in a collision cell taking some time to reach equilibrium when the operating condition is changed.
