I. Introduction to enhanced liquid extraction:

Enhanced liquid extraction is one of the common water sample pretreatment methods, but the traditional split funnel extraction method has a low degree of automation, time-consuming, labor-intensive, easy to inhale toxic exhaust. And strengthen the liquid extractor so that the organic phase and the aqueous phase in the two containers moving up and down, simulating the artificial extraction process, the degree of automation is high, the use of a short period of time, can be widely used in enterprises and other chemical laboratories need to be extracted and processed places, such as volatile phenols and petroleum extraction operations.

II. strengthen the advantages and disadvantages of liquid extraction:

Intensive liquid extraction is a very common pretreatment instrument in laboratories at all levels. Manual hand extraction is labor intensive, inefficient and carries a large risk of inhaling toxic gases. Currently, the common enhanced liquid extraction instruments are mainly reciprocating shock, 360 degree flip, stirring and jetting with different disadvantages. The first two need to be manually deflated, which can only save the shock process, and the latter two are prone to evaporation of extraction solvents and are not easy to clean. Intensive liquid extractor absorbs the advantages of similar products, avoids the shortcomings, and adopts the principle of closed airflow oscillation internal circulation. It can be started and automatically extracted with a button; the extraction process does not need to be deflated; the extraction ends with automatic cleaning; the extraction waste liquid is adsorbed through the activated carbon adsorption tank and automatically discharged, and all the running commands and parameters can be operated through LCD touch screen. It has the advantages of high degree of automation, saving time and labor, energy saving and environmental protection. Applicable to water quality monitoring, such as water oil, volatile phenols.

III. The working environment of the enhanced liquid extractor:

Enhanced liquid extractor should be placed in a clean, well-ventilated room. The working table should be firm and stable, the instrument should be well grounded. When using organic solvents that are unfavorable to the human body as extractants, it is recommended that the extractor be placed in a fume hood to reduce the harm to the human body. We must pay attention to the correct operation when using the liquid-liquid extractor to ensure our safety.
