Presented is a mass spectrometer comprising an ion path along which ions are transported between different sections of the mass spectrometer, and further comprising an arrangement with a receptacle being located along the ion path in the mass spectrometer and a complementary mount for carrying a removable ion-optical assembly, such as a carrier of electrodes for a MALDI ion source, wherein the mount can be removed from and reinserted into the receptacle in a plane approximately perpendicular to an ion path axis.

Arrangement for a removable ion-optical assembly in a mass spectrometer

A device for use in a mass spectrometer allows an ion-optical assembly to be removed, cleaned and reinserted with relatively high positioning accuracy. In particular, the device obviates the need for complex adjustments requiring special knowledge after the reinsertion. The objective is achieved by an arrangement comprising a receptacle and a mount for a removable ion-optical assembly in a mass spectrometer. Favorable implementations provide a mount and a receptacle with three pairs of complementary support elements, the three support elements on the receptacle form a support plane, and, when the mount is inserted into the receptacle, at least two pairs of support elements are engaged and the mount is aligned with respect to the support plane with the aid of the third pair of support elements.
