Description

technical field [0001] The invention relates to the field of chemical analysis experiments, in particular to a hollow fiber extraction device. Background technique [0002] Hollow fiber extraction is a new type of sample pretreatment technology, a type of liquid phase microextraction, which has the advantages of rapidity, environmental friendliness, high enrichment multiple, and good purification effect. The hollow fiber extraction currently reported in the literature is mainly to cut the hollow fiber into small pieces, seal one end, insert the other end into a syringe needle, inject the organic solvent into the hollow fiber membrane, and extract the target substance in the solution. Because there is no special device, the operation is inconvenient, the operation requirements of the testing personnel are high, and the reproducibility of the pre-treatment is not good, so it is only suitable for gas phase, gas and gas detection instruments. Contents of the invention [0003...
