High-efficiency concentrated solution-liquid micro-extraction device and method capable of seamlessly combining chromatographic analysis

The invention discloses a high-efficiency concentrated solution-liquid micro-extraction device and method capable of seamlessly combining chromatographic analysis. A trace extraction liquid collectionbottle is arranged at the upper end or the lower end of the device, since a micro-extraction bottle is connected through an extraction enrichment device with an opening gradually convergent, a sampleis automatically positioned on an upper layer or a lower layer after extracted and layered, the collecting effect of an extracting solution containing a high-concentration component can be greatly improved through further enrichment by the extraction enrichment device, the concentration and enrichment time of the sample is greatly improved under the condition that the extraction rate is not greatly changed, and the detection limit and the determination limit of sample determination are greatly reduced; and the purpose that a same instrument can be used for measuring trace substances is achieved, the measuring range of the instrument is greatly enlarged, and therefore work of high-grade instruments is completed through low-grade cheap instruments, and trace substances measured through thehigh-grade instruments are measured through low-grade cheap instruments.
