NMR MAS Rotor Detection via Contactless Sensor Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing NMR MAS spectrometer systems require mechanical displacements and additional moving components for contact-based detection of the NMR MAS rotor, which complicates the detection process and is not suitable for all axial orientations.
Innovation Solution
A contactless detection system using a sensor apparatus with a sensor line that transmits signals based on the relative position of the transport container to the probe head, eliminating the need for mechanical components and allowing secure detection of the NMR MAS rotor within the shuttle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a contact-based detection system with mechanical components is used to detect the NMR MAS rotor, then the detection can be performed reliably, but the device complexity increases and mechanical displacements are required
Solution Approach 1:
The patent replaces the mechanical contact-based detection system with a contactless sensor-based detection system. The sensor detects the presence of the NMR MAS rotor in the shuttle without requiring mechanical contact or displacement, thereby reducing device complexity while maintaining detection reliability.
2Reliability
If mechanical components are used for detection, then the detection can be performed, but the system is not suitable for all axial orientations
Solution Approach 1:
The contactless sensor-based detection system replaces the mechanical detection system, enabling the system to detect the NMR MAS rotor regardless of axial orientation. The sensor can detect the rotor's presence without requiring specific mechanical alignment or orientation, thereby improving adaptability while maintaining detection capability.
3Device complexity
If contactless detection is implemented, then the device complexity is reduced and adaptability is improved, but the detection precision may be affected
Solution Approach 1:
The sensor creates an informational copy or signal representation of the rotor's presence state without requiring physical contact. This allows the detection system to maintain precision by detecting the rotor's presence through its electromagnetic or other non-mechanical signature, achieving both reduced complexity and maintained precision.

AI summary
A transport device for transporting an NMR sample to a probe head (16), having a shuttle (15) and a locking apparatus (3) for the rotor (5), which, when attaching the shuttle to the probe head, releases the rotor, and having a detecting apparatus for detecting the rotor in the shuttle. The probe head has a positioning apparatus (2), which holds the probe head in a defined measuring position relative to the shuttle. The detecting apparatus includes a sensor line, which transmits a signal dependent on the position of the probe head to the shuttle's end. A first portion (1a) of the sensor line is mounted inside the shuttle and extends from the rotor in a transport state to the end of the shuttle. A second portion (1b) of the sensor line is mounted inside the probe head and, in the measuring position, is directly adjacent to the first portion.
