Description

technical field

[0001] The invention relates to the technical field of chemical separation devices, in particular to a gas-boiling stable extraction device. Background technique

[0002] Liquid / liquid extraction refers to the process of transferring components from one solution to another by using the difference in distribution coefficient of components in two immiscible solutions. Generally, the process of transferring a component from an aqueous phase to an organic phase is called extraction. Liquid / liquid extraction is a commonly used method for sample pretreatment. Through liquid / liquid extraction, desired sample components can be selectively separated, enriched and purified from liquid mixtures. Conventional liquid / liquid extraction is operated in a separatory funnel, and the extraction process needs to be composed of steps such as shaking, mixing, standing, layering, and two-phase separation. In order to improve the extraction efficiency, it is usually necessary to ...
