Solid-phase extraction column used cooperatively with GC-FID instrument and application thereof

The invention discloses a solid-phase extraction column used cooperatively with a GC-FID instrument and application thereof. The solid-phase extraction column used cooperatively with the GC-FID instrument is applied to pretreatment of a to-be-detected sample for mineral oil contaminant detection of food. The solid-phase extraction column comprises a hollow glass column and a plurality of glass fiber sieve plates which are arranged in the hollow glass column and isolate the interior of the hollow glass column into a silver nitrate impregnated silica gel filling space used for filling of silver nitrate impregnated silica gel, an anhydrous sodium sulfate filling space used for filling of anhydrous sodium sulfate and an alumina filling space used for filling of alumina, wherein the silver nitrate impregnated silica gel filling space, the anhydrous sodium sulfate filling space and the alumina filling space are successively arranged from top to bottom. Through pretreatment of the sample for analysis of mineral oil contamination of food by using the solid-phase extraction column, analysis pollution can be effectively reduced, and repeatability and accuracy of sample detection are improved; and the solid-phase extraction column is applicable to most food.
