Problems solved by technology
[0002] At present, the common hollow fiber membrane micro-extractor adopts micro-extraction technology. Micro-extraction technology is a technology for extracting trace organic compound residues. It includes material-liquid phase (sample), organic phase, and receiving phase. The existing hollow fiber Membrane micro-extractors can only extract three groups of samples at a time. If multiple groups of samples need to be extracted for comparative experiments, the test efficiency is low. Each group of samples in hollow fiber membrane micro-extractors usually includes multiple samples. The solution that needs to be stirred includes three parts of sample, organic phase and receiving phase. Each group of samples is usually only powered by a magnetic stirrer for stirring, because a group of samples contains multiple parts of the solution that needs to be stirred, and the existing The number of micro-extractors is limited. Once the agitator starts to work, all the agitators are in working condition, even the agitator in idle state is also in working condition, which increases the burden on the motor and reduces the service life of the motor
