一种滴管固相萃取装置和方法以及该装置的制备方法
摘要：
本发明公开了一种滴管固相萃取装置，包括动力装置和固相萃取容器，所述滴管固相萃取装置应用于非水介质固相萃取，所述固相萃取容器的制作材料为玻璃，所述固相萃取容器中盛装的溶剂为非极性或弱极性溶剂，所述动力装置设在固相萃取容器的上方，通过挤压动力装置实现所述固相萃取容器内的固相萃取。本发明还包括一种滴管固相萃取方法和一种滴管固相萃取装置的制备方法和应用。本发明利用玻璃容器作为固相萃取容器，有效规避了传统塑料容器在进行非水介质萃取时塑化剂的干扰。
摘要（英）：

The invention discloses a dropper solid phase extraction device which comprises a power device and a solid phase extraction container. The dropper solid phase extraction device is applied to a non-aqueous medium solid phase extraction and the solid phase extraction container is made from glass. A solvent held in the solid phase extraction container is a non-polar or weakly polar solvent; the power device is arranged above the solid phase extraction container, and solid phase extraction in the solid phase extraction container is realized by squeezing the power device. The invention also comprises a dropper solid phase extraction method and a preparation method and application of the dropper solid phase extraction device. By taking the glass container as the dropper solid phase extraction container, interference of a plasticizer during non-aqueous medium extraction in a conventional plastic container is effectively avoided.
