Migration pool and using method thereof

The invention provides a migration pool and a using method thereof. The migration pool comprises a pad cover, a U-shaped soaking pool and a soaking locking device, wherein the soaking pool comprises asample arm, a liquid addition arm and a pool body, two ends of the pool body are separately connected to the lower end of the sample arm and the lower end of the liquid addition arm, and the pad cover covers an opening of the upper end of the sample arm in a buckling mode and is fixed by the soaking locking device. Accurate control over S/V (the ratio of the contact area of food contact materialsand products to the size or mass of food simulants) is facilitated, interference factors are less, the migration pool and the using method thereof are suitable for reflux condensation, functional diversity is achieved, and operation is convenient. 本发明提供了种迁移池及其使用方法，迁移池包括垫盖、呈U型的浸泡池、浸泡锁固装置，所述的浸泡池包括样品臂、加液臂、两端分别连接样品臂下端和加液臂下端的池身，垫盖扣盖在样品臂上端开口且通过浸泡锁固装置固定。便于精确控制S/V，并且干扰因素少、适合冷凝回流、功能多样、操作简便。
