Problems solved by technology

[0005] Weaknesses of current technology: NMR and chromatography are difficult to combine
Such a collection process will lead to a large loss of substances, especially the nuclear magnetic resonance itself is an analytical instrument with low sensitivity and low effective utilization, so the substances after chromatographic separation are basically so small that they cannot be measured
This is why chromatography-NMR is difficult to achieve effectively

Embodiment Construction

[0021] The usual nuclear magnetic resonance system is composed of magnets, gradient coils, probes, computers and circuit control parts connected by connections, and the liquid chromatography system is composed of chromatographic columns, high-pressure pumps, valves, sample syringe cleaning liquid solvents connected by pipelines. in,

[0022] 1. Magnets: The main components of nuclear magnetic resonance are divided into two categories: conventional magnets and superconducting magnets. Conventional magnets are magnets that use common magnetic steel or current to form a loop through ferromagnetic materials to obtain a higher magnetic field (<2.3T). A superconducting magnet is a magnet with a hollow superconducting coil that utilizes the zero resistance of superconducting materials at low temperatures, has the ability to flow a super-strong current, and generates a super-high magnetic field (5-20T). It can and utilizes zero resistance to form closed highly stable current without ...

Abstract

An image and spectrum analyzer is composed of high efficient liquid phase chromatograph system and nuclear magnetic resonance system. It is featured as setting chromatographic column in central hole of measuring probe placed between two gradient coils set between two cylindrical magnetic poles if normal magnet is applied or setting chromatographic column in central hole of measuring probe placed in gradient coil set in cylindrical superconductive magnet if superconductive magnet is applied.

Description

technical field [0001] The invention belongs to the technical field of chemical analysis, and in particular relates to a high-performance liquid chromatography nuclear magnetic resonance imaging spectrum analyzer. Background technique [0002] At present, nuclear magnetic resonance chemical analysis instruments and high-performance liquid chromatography analysis instruments are all separate. [0003] NMR chemical analysis instruments include: Swiss Bruker Company, Japan JEO Company, and American Varian Company. [0004] High-performance liquid chromatography analysis instruments abroad include: American Agilent (Agilent), Waters Corporation, etc. The products of the above-mentioned companies are imported in China. [0005] Weaknesses of current technology: NMR and chromatography are difficult to combine. The reason is that the prior art uses chromatography to separate and collect, and then put the collected substances into nuclear magnetic resonance for measurement. Such...
