Abstract
The utility model relates to a flow injection online solid phase extraction micro-column, essentially comprising a left quartz wool (1), an absorption filler (2), a left conical column (3), a right conical column (4), a right hole (5), a right quartz wool (6) and a left hole (9). The flow injection online solid phase extraction micro-column is characterized in that the left quartz wool (1) is filled in the left hole (9), the right quartz wool (6) is filled in the right hole (5), the right conical column (4) and the left conical column (3) are connected in plug-in manner, and the absorption filter (2) is filled in the right conical column (4) and the left conical column (3).
Description
Technical field
The utility model relates to a kind of online SPE microtrabeculae of flow injection that is used for enrichment environment water sample trace contaminant.
Background technology
Inorganic and organic pollution content in the environmental water sample is humble, and the separation and concentration before analyzing is extremely important.SPE is a kind of effective enrichment method, but commercial solid-phase extraction device is as extraction tube and extracting disk complex operation, expensive.The adsorption stuffing of commercialization solid phase extraction column generally is difficult for changing, and is unfavorable for that the user by investigating various new packings, improves selectivity and the rate of recovery of SPE to enrichment of analytes.Therefore, develop a kind of simple, economic, solid-phase extraction device of being easy to automation that is applicable to the environmental water sample pollutant, can further enrich and develop solid phase extraction techniques.
Summary of the invention
In order to improve commercialization solid-phase extraction device above shortcomings, the utility model intends providing a kind of self-control that is easy to, the online SPE microtrabeculae of flow injection simple to operate, the expansion SPE is the application aspect the inorganic and organic pollution on-line preconcentration of trace in environmental water sample.
The technical scheme that its technical problem that solves the utility model adopts is: the online SPE microtrabeculae of flow injection is made up of left silica wool, adsorption stuffing, left tapered pole, right tapered pole, right aperture, right silica wool, right macropore, left macropore, left aperture, it is characterized in that: left aperture place is filled with left silica wool, right aperture place is filled with right silica wool, right tapered pole links to each other with plug-in type with left tapered pole, is filled with adsorption stuffing in right tapered pole and the left tapered pole.
Advantage of the present utility model is: the material of the online SPE microtrabeculae of (1) preparation flow injection is easy to get, and is easy to self-control, and is with low cost.(2) the online SPE microtrabeculae of flow injection is reusable, is easy to change adsorption stuffing.(3) coupling of online SPE microtrabeculae of flow injection and flow injection can be connected to the flow injection stream by flexible pipe with the sharp mouth place of left tapered pole or right tapered pole and realizes, sample solution enters from left aperture or right aperture, pollutant remains in the adsorption stuffing, and waste liquid flows out from right aperture or left aperture.
The beneficial effects of the utility model are: (1) can be incorporated into the SPE system with various novel absorption materials, thereby expand the application of adsorption stuffing in the SPE field, (2) online SPE microtrabeculae of flow injection and flow injection stream mate fully, in conjunction with flow injection enrichment program, can realize that the quick on-line preconcentration of pollutant detects in the water sample.
Description of drawings
Fig. 1 is the online SPE microtrabeculae of a flow injection profile.
Each label declaration is as follows among Fig. 1:
(1) left silica wool, (2) adsorption stuffing, (3) left tapered pole, (4) right tapered pole, (5) right aperture, (6) right silica wool, (7) right macropore, (8) left macropore, (9) left aperture.
The specific embodiment
In Fig. 1, left side tapered pole 3 left ends have the left aperture 9 of a circle, right-hand member has the right macropore 7 of a circle, left side tapered pole 3 internal diameter from left to right increases gradually, right tapered pole 4 left ends have the left macropore 8 of a circle, right-hand member has the right aperture 5 of a circle, right tapered pole 4 internal diameter from left to right reduces gradually, right tapered pole 4 and left tapered pole 3 all are injection molded by macromolecular material, the left end of right tapered pole 4 presses closer on left tapered pole 3 inwalls, in right tapered pole 4 and the left tapered pole 3 adsorption stuffing 2 is housed, and the external diameter of left macropore 8 is slightly less than the internal diameter of right macropore 7, aperture 9 places, a left side are filled with left silica wool 1, and right aperture 5 places are filled with right silica wool 6.
