Embodiment Construction

[0064] figure 1 A first form of construction of a MAS-NMR rotor system 100 for the invention is shown, comprising a rotor 1 in which a measurement substance is arranged in solid or semisolid form (eg powder or gel) and comprising a stator 2 . exist figure 1 The stator 2 is shown above (together with the components of the stator holder 32), in figure 1 Rotor 1 is shown in the center and in figure 1 The entire MAS-NMR rotor system 100 with the rotor 1 and the stator 2 (together with the components of the stator holder 32 ) is shown below. The MAS-NMR rotor system 100 and the stator holder 32 are part of a probe assembly 200 according to the invention.

[0065] The stator 2 includes a first pneumatic bearing (here a radial bearing) 3 , a second pneumatic bearing (here a radial bearing) 4 and a third pneumatic bearing (here an axial bearing) 5 . The rotor 1 is mounted rotatably about an axis of rotation RA within the stator 2 .

[0066] The rotor 1 comprises a cylindrical sec...

Abstract

An MAS NMR probe head arrangement has a stator (2) aligned along an axis of rotation (RA) to support a rotor (1), a stator mount (32), and a RF coil arrangement (21) to emit / receive RF pulses into / from the measurement substance (40) in the rotor. The stator mount has a stator bearing (41) into which the stator can be axially inserted and extracted. The stator, when inserted, passes through the RF coil arrangement (21), and can be fed through the RF coil arrangement (21). A mechanism fixes the stator axially in the stator bearing (41) when inserted. This arrangement enhances both ease of assembly and maintenance of the arrangement.

Description

technical field [0001] The invention relates to a magic-angle rotating nuclear magnetic resonance probe assembly comprising a stator, a stator holder, and a high-frequency coil assembly, the stator being oriented on an axis of rotation and serving to support a rotor with a measuring substance, the high-frequency coil assembly For injecting high-frequency pulses into the measuring substance in the rotor and / or for receiving high-frequency signals from the measuring substance in the rotor. Background technique [0002] Such a magic angle rotating NMR probe assembly is known from US 7,915,893 B2. [0003] Nuclear magnetic resonance (=NMR, nuclear magnetic resonance) spectroscopy is a powerful instrumental analysis method by means of which the chemical constituents of the measured substance (sample) can be detected. In this case, the measurement substance is exposed to a strong static magnetic field, which causes an orientation of the nuclear spins in the measurement substance....
