Abstract

The invention relates to an automatic sampler of a nuclear magnetic resonance spectrometer. The automatic sampler comprises an engine base and a sample case; the sample case comprises a transmission chain, a synchronous belt, a transmission mechanism, a guide groove and a backplane component; the backplane component comprises a backplane, a semicircle fixed connection pipe, a semicircle mobile connection pipe and a slide block; a connector with a seal ring is arranged on the engine base; a sample inlet pipe placed in the magnet field is fixedly connected under the connector; a direct current motor movably connected with the transmission mechanism, a parallel air claw for catching the fixed connection pipe, a push rod cylinder for pushing the mobile connection pipe, a plunger cylinder connected with a tapered plunger, a barcode scanner, a diffuse reflection sensor for detecting a glass pipe of a loaded sample, a serial port plug I connected with an MCU control board, and a fault alarm are installed on the frame. The automatic sampler of the nuclear magnetic resonance spectrometer has small volume, low cost, convenience in installation, high degree of automation, and is convenient, safe and reliable to control.

Description

technical field [0001] The invention relates to a nuclear magnetic resonance spectrometer, in particular to a special automatic sampler for analyzing samples by the nuclear magnetic resonance spectrometer. Background technique [0002] NMR spectrometer is a magnetic analytical instrument that utilizes the differences in the properties of the nuclei of different elements to analyze substances. It is widely used in the structural determination of compounds, quantitative analysis and zoological research. [0003] The high degree of automation of the autosampler can save a lot of manpower and time, and at the same time reduce the error caused by human operation. It is an indispensable supporting instrument for mass analysis of samples by nuclear magnetic resonance spectrometer. [0004] Existing NMR spectrometer autosamplers are mainly grasped by manipulators, and there are two types: one is a separate autosampler rack, and a transmission chain with a large transmission space is...
