Embodiment Construction

[0029] The present invention addresses the damage-free assembly of high-frequency seals into nuclear magnetic resonance probes.

[0030] Such a nuclear magnetic resonance probe 1 type comprises one or more high-frequency coils 2 arranged around the vertical axis of symmetry z of the nuclear magnetic resonance electromagnetic coil assembly and a high-frequency network 3 which is connected by Surrounded by a device 4 for shielding against external high-frequency radiation, which comprises an electrically conductive shielding tube 5 arranged along the z-axis, which can surround the high-frequency coil 2 and the high-frequency network 3 in the z-direction towards the substrate 6 move.

[0031] The invention is characterized in that a shielding plate 7 is arranged at an axial distance from the base plate 6, and that a clampable high-frequency seal 8 is arranged between the shielding plate 7 and the shielding tube 5 in the assembled state, so that The high-frequency seal is geometr...

Abstract

The invention relates to a nuclear magnetic resonance probe with one or more high-frequency coils arranged around a vertical axis of symmetry and with a high-frequency network, which are surrounded by means for shielding external high-frequency radiation, said for shielding the external The device for high-frequency radiation comprises a shielding tube which can be moved around the high-frequency coil and the high-frequency network in the z-direction towards the substrate. A shielding plate is arranged at an axial distance from the base plate, between the shielding plate and the shielding tube, in the assembled state, a clampable high-frequency seal is arranged, which is geometrically designed such that : In the first assembly state, the shielding tube can move on the shielding plate without clamping and without force, and in the second assembly state, the high-frequency seal can be mechanically clamped between the shielding plate and the shielding tube, This ensures an electrically conductive connection to the shielding tube in the circumferential direction of the shielding plate. The shielding tube can thus be assembled and disassembled without stress. The invention also relates to a nuclear magnetic resonance measuring device with such a nuclear magnetic resonance probe.

Description

technical field [0001] The invention relates to a nuclear magnetic resonance (NMR) probe with one or more high-frequency (HF) coils arranged around a preferably vertical z-axis and with a high-frequency network, the high-frequency coils and the The high-frequency network is surrounded by a device for shielding external high-frequency radiation, which device includes a conductive shielding tube arranged along the z-axis, which can move around the high-frequency coil and the high-frequency network in the z-direction towards the substrate. [0002] Such an arrangement is, for example, published by Bruker BioSpin AG (Bruker BioSpin AG, No. 26, Edustri Street, Flanders, Switzerland, CH-8117) in 2007 in the company publication "HF immunity modifications" (reference [1]) is known. Background technique [0003] NMR spectroscopy is an effective method for instrumental analysis. Here, radio-frequency pulses are irradiated into a test sample in an intense static magnetic field, and t...
