Novel microextraction high-throughput magnetic stirring system

Abstract

The invention discloses a novel microextraction high-throughput magnetic stirring system. The system comprises an extractor and a magnetic stirring system, the stirring system utilizes a motor to drive a worm to rotate, through turbine-worm transmission, the power of the motor is transmitted from the worm to turbines to drive the turbines to move, finally, rotary tables on turbine shafts are driven to rotate, thus providing corresponding power for stirring, the number of the turbines can be set according to the number of solutions needing stirring, thus better meeting the stirring requirement.The magnetic stirring system can achieve stirring of multiple groups of samples and stirring of multiple samples in a group of samples, realizes the purpose of stirring in high-throughput detection,the stirring system is provided with a plurality of rotary tables, and each rotary table is equipped with a pair of magnetic bodies, so that power is provided for each solution needing stirring, and each group of samples are stirred more uniformly.

Description

technical field [0001] The invention relates to a hollow fiber membrane micro-extractor, in particular to a novel micro-extraction high-flux magnetic stirring system. Background technique [0002] At present, the common hollow fiber membrane microextractor adopts liquid-liquid-liquid microextraction technology. Liquid-liquid-liquid microextraction technology is a technology for extracting trace organic compound residues, which includes liquid phase (sample), organic phase, In the receiving phase, the existing hollow fiber membrane micro-extractor can only extract three groups of samples at a time. If multiple groups of samples need to be extracted for comparative experiments, the efficiency of the test is low. At the same time, each hollow fiber membrane micro-extractor A group of samples usually includes multiple solutions that need to be stirred. There are three parts of the sample, the organic phase and the receiving phase that need to be stirred, and each group of sample...

[0002] At present, the common hollow fiber membrane microextractor adopts liquid-liquid-liquid microextraction technology. Liquid-liquid-liquid microextraction technology is a technology for extracting trace organic compound residues, which includes liquid phase (sample), organic phase, In the receiving phase, the existing hollow fiber membrane micro-extractor can only extract three groups of samples at a time. If multiple groups of samples need to be extracted for comparative experiments, the efficiency of the test is low. At the same time, each hollow fiber membrane micro-extractor A group of samples usually includes multiple solutions that need to be stirred. There are three parts of the sample, the organic phase and the receiving phase that need to be stirred, and each group of samples is usually only powered by a magnetic stirrer for stirring, because a group of samples contains multiple parts. The solution that needs to be stirred, and the farther away from the center of the magnetic stirrer, the smaller the stirring power will be, and the phenomenon of uneven stirring will occur. Therefore, it is necessary to have a power source that can provide multiple parts of the liquid that needs to be stirred in a group of samples. A magnetic stirring system that allows each liquid in a set of samples to be fully stirred
