Abstract
A method for producing a highly precise and inherently stable analyzer system for a multipole mass filter, wherein a tube of material that is electrically poorly conductive and thermally softenable is put over a core which is precise in size, has a higher expansion coefficient and has parallel grooves. The tube material is joined to the grooves of the core by heating and, subsequently, after cooling for the purposes of solidifying, is removed from the core with the impressed tube indentations. Before the tube is heated, layers of electrically higher conductive metallic components, which can be easily connected to the softenable tube material, are applied between the core and the tube in the region of the grooves. The layer material is connected to the tube material when the tube is softened and joined to the grooves of the tube. When removing the tube that has been shaped in this manner, the layers connected to the impressed tube indentations are also removed from the core. An analyzer system produced according to the inventive method is also disclosed.
