A kind of in-situ separation detection nuclear magnetic resonance radio frequency probe front end and preparation method thereof

Abstract

The invention relates to an in-situ separation and detection nuclear magnetic resonance radio frequency probe front end and a preparation method thereof. The charged particle filter pipe, the separation waste liquid discharge pipe and the bifurcation and split flow cooperation of the sample detection pipe, in a vertical magnetic field environment, charged The paramagnetic particles are acted by the radially outward Lorentz force, which can effectively shunt the charged particle filter pipe, the separation waste liquid discharge pipe and the sample detection pipe at the intersection, so that the separated paramagnetic particles The solution is discharged from the separation waste liquid discharge pipe. The invention has a simple and efficient magnetic substance filtration and separation structure, and has a flexible customized sample pipeline design, which is convenient to modify and adjust according to the needs of the experiment, effectively improves the detection signal-to-noise ratio, and can meet the requirements of various in-situ nuclear magnetic resonance detection. The invention is prepared by 3D printing, which can improve design flexibility, greatly improve efficiency, and reduce labor costs.

Description

technical field [0001] The invention relates to the technical field of nuclear magnetic resonance, and more specifically relates to a front end of an in-situ separation detection nuclear magnetic resonance radio frequency probe and a method for preparing the front end of an in-situ separation detection nuclear magnetic resonance radio frequency probe. Background technique [0002] NMR is non-destructive and is an important means of modern analysis and detection technology. It has been widely used in many fields such as physics, chemistry, biology, medicine and food detection. As one of the core components of nuclear magnetic resonance equipment, the front end of the radio frequency probe composed of radio frequency coils, radio frequency circuits and pipelines in the sample detection area largely determines the performance of the instrument. [0003] The nuclear magnetic resonance radio frequency coil can convert the pulse sequence electrical signal into a high-frequency ele...

Problems solved by technology

However, for the reaction of magnetic substances, only the conventional external non-situ separation and filtration technology can be used, so the in-situ NMR monitoring of the experimental system cannot be carried out, which makes the relevant detection and analysis difficult.

[0010] Most of the existing in-situ separation technologies need to add additional devices, perform complex construction operations, or create a special separation environment, and it is difficult to apply to in-situ NMR detection with strong magnetic fields and small cavities.
