Abstract
A mass spectrometer has a manifold and at least one ion optical assembly that is composed of a support and electrodes attached to the support. The support is aligned to at least one reference surface machined integrally with the manifold such that the number of interfaces between the reference surface of the manifold and the electrodes is minimized. With such a design the positional and/or alignment precision of ion optical assemblies in a mass spectrometer can be improved.
Claims17
A mass spectrometer comprising a manifold having walls and a base plate forming part of a housing of the mass spectrometer, and at least one multipole ion optical assembly, comprising:
- the multipole ion optical assembly having a support with two sides and a plurality of electrodes, all electrodes being attached directly to one side of said support;
- and
- at least one reference surface that is integrally machined with the manifold;
- wherein the side of the support to which the plurality of electrodes is directly attached contacts, and thus is aligned to, the at least one reference surface.
A mass spectrometer comprising a manifold having walls and a base plate forming part of a housing of the mass spectrometer, and at least one multipole ion optical assembly, comprising:
- the multipole ion optical assembly having a support with an adjustment surface, and a plurality of electrodes, all of which are attached and aligned to said adjustment surface;
- and
- a reference surface being a substantially planar surface at a protruding feature having the shape of one of a post, step and plateau, machined integrally with the manifold;
- wherein a side of the support opposing the adjustment surface contacts the reference surface and thus aliens the adjustment surface to the reference surface.
A mass spectrometer comprising a manifold having walls and a base plate forming part of a housing of the mass spectrometer, and at least one multipole ion optical assembly, comprising:
- the multipole ion optical assembly having a support with two sides and a plurality of electrodes, all of which are attached to a first side of said support, a pair of said electrodes of the plurality of electrodes being directly attached to said first side of said support;
- and at least one reference surface that is integrally machined with the manifold;
- wherein the side of the support to which the electrodes are directly attached contacts, and thus is aligned to, the at least one reference surface.
