The extractive analysis of organic pollution in matrix；The utility model apparatus structure is simple, optional feature
Few, easy to operate, it is not necessary to applying power, extracting operation cost is greatly reduced, is suitable for
In batch and on-the-spot fast operating；The utility model apparatus structure is stable, and batch processing decreases
Manual operation, compared with conventional solid extraction equipment, improves the stability of operation, reappearance
Extraction efficiency with method.
Accompanying drawing explanation
The utility model has a drawings described below:
Fig. 1 is extraction column structural representation described in the utility model；
Fig. 2 is the utility model structural representation；
Fig. 3 is the structural representation of bracing frame described in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As in figure 2 it is shown, a kind of novel solid-phase extraction device, including extraction column 10 and bracing frame,
As it is shown in figure 1, described extraction column 10 includes column jecket 1, extraction column outlet 5 and piston 9；Institute
State piston 9 and be installed on described column jecket 1 inside, the external diameter of piston 9 and the internal diameter phase of column jecket 1
Adaptive；Described column jecket 1 is made up of the macromolecular material such as polyethylene or polypropylene, have inertia,
Can tolerate various polarity and non-polar organic solvent feature；In described column jecket 1 the most successively
Import sieve plate 2, solid phase extraction filler layer 3 and exit sieve plate 4 are set；Wherein import sieve plate 2
With exit sieve plate 4 be disposed to prevent the filler in solid phase extraction filler layer 3 from leaking outside.
The aperture of described import sieve plate 2 and exit sieve plate 4 is 10-200 μm, thickness 1-5mm.
As it is shown on figure 3, support frame as described above includes top board 11, side supports frame 13 and collet 12；
Described side supports frame 13 has two；Two side supports framves 13 and top board 11 and collet 12
Composition " mouth " font frame,
The threaded depression bar in middle part 14 of described top board 11, the top of described depression bar 14 is fixed
Connecting wind 6, the bottom of described depression bar 14 is fixing connects lifter plate 7；
It is fixedly installed extraction column support 8 between two described side supports framves 13, described
Arranging post holes 15 on extraction column support 8, described extraction column 10 is placed in described post holes 15.
Detachable connection between described extraction column support 8 and described side supports frame 13, permissible
Model according to extraction column 10 is different, is replaced extraction column support 8, meanwhile, in order to
