Description

Technical Field

[0001] The utility model relates to the technical field related to monitoring devices, in particular to a Soxhlet extraction nuclear magnetic resonance monitoring device. Background Art

[0002] Soxhlet extraction is a commonly used solid-state sample extraction method, mainly used to extract organic compounds from solid materials. This method extracts the target compound from the solid sample into the solvent through a continuous cycle of solvent distillation and condensation. The nuclear magnetic resonance monitoring device is a device used to monitor chemical reactions or changes in the properties of a substance. It uses the principle of nuclear magnetic resonance to analyze the signals of atomic nuclei (such as hydrogen nuclei or carbon nuclei) in the sample, thereby providing information about molecular structure, dynamic processes and chemical environment. A device that combines Soxhlet extraction with nuclear magnetic resonance monitoring can achieve real-time monitoring of the extraction efficiency of compounds during the extraction process. This device usually includes a Soxhlet extractor and a nuclear magnetic resonance spectrometer. During the extraction process, the extracted solvent and compound will be sent to the nuclear magnetic resonance spectrometer for analysis, thereby monitoring the changes in extraction efficiency and compound concentration in real time.

[0003] The nuclear magnetic resonance probe is a key component in existing nuclear magnetic resonance spectrometers. However, during the use of the nuclear magnetic resonance probe, the sample tube needs to be calibrated so that the sample tube is located at the center of the probe, which takes a long time and reduces the monitoring efficiency. Therefore, it is necessary to propose a Soxhlet extraction nuclear magnetic resonance monitoring device. Utility Model Content

[0024] Working principle: When using the Soxhlet extraction nuclear magnetic resonance monitoring device, first, when the glass tube 2 is connected to the probe body 1, pull the limit plates 13 on both sides to drive the anti-slip pads 14 to fit the outer wall of the glass tube 2, and at the same time drive the movable block 9 to move inside the return plate 6.
