SOLID PHASE EXTRACTION COLUMN, PREPARATION METHOD THEREFOR, AND CHEMICAL SAMPLE PRE-PROCESSING METHOD BASED ON SOLID PHASE EXTRACTION COLUMN

WIPO Patent Application WO/2016/045032

A1

A solid phase extraction column, a preparation method therefor, and a chemical sample pre-processing method based on the solid phase extraction column. The solid phase extraction column comprises a separation column, and a solid phase extraction agent filled within the separation column, the solid phase extraction agent being graphene or modified graphene. The solid phase extraction column is prepared via loading of the solid phase extraction agent into the separation column, and vibration compaction of the solid phase extraction agent, the solid phase extraction column is used to pre-process a chemical sample, a highly effective separation effect is implemented, and the problem of data distortion caused by it not being possible for a target component to be detected in subsequent detection or it not being possible to detect a true value is prevented.
