Separation, purifying and the enrichment of sample, main purpose are to reduce sample substrate interference, raising detection sensitivity.For convenience,
Solid Phase Extraction generally uses solid phase extraction column, there is various specifications according to different needs.Meanwhile in order to meet different samples
Process demand needs to fill the independent filler of two classes in a variety of situations, so that two class fillers are filled in two independent columns
In body.Filler is usually successively compacted and is filled by sieve plate separation by existing dual phase filler solid-phase extraction column, however
This mode has the disadvantage that the contact area of (1) sample and filler is small, and adsorbance is low；(2) eluent washing in filler
De- speed is slow, and need extraneous pressure when necessary: (3) operating time is long, and extraction efficiency is low.It is therefore desirable to two-phase extraction column into
Row further research.
Utility model content
In order to solve the above technical problem of the existing technology, the utility model provides a kind of universal dual phase filler
Solid-phase extraction column.
To achieve the goals above, the utility model uses following technical scheme:
A kind of universal dual phase filler solid-phase extraction column, including column tube, the first push rod and the second push rod, the column tube both ends
For hatch frame, first push rod and the second push rod protrude into column tube from the opening at column tube both ends respectively and make with respect to column tube past
Multiple movement, the middle part of the column tube are equipped with the first sieve plate, are filled with the first filler respectively in the column tube of first sieve plate two sides
With the second filler；Column tube inner wall close to first sieve plate one end is equipped with the outlet tube that is connected with column tube, the outlet tube with
Column tube is mutually separated by the second sieve plate, and the outlet tube side wall close to second sieve plate one end is equipped with the rotation for extending vertically through outlet tube
Plug, the cock are slidably arranged on outlet tube and rotate relative to outlet tube, protrude into the middle part of the cock in outlet tube and are equipped with and go out
Liquid in liquid pipe moves towards consistent through-hole.
Further, the end of the outlet tube bends downward the liquid outlet for being formed in parallel with column tube, and bending place is four points
One of arc structure.
Further, the liquid outlet is equipped with liquid outlet lid.
Further, the plane of the liquid outlet being directed away from where the first sieve plate.
Further, the outlet tube is located in the compressed altitude range of filler in the column tube corresponding to it.
The utility model has the advantages that the utility model provides a kind of universal dual phase filler solid-phase extraction column, it is described in the utility model
Solid-phase extraction column have the advantage that
1, solid-phase extraction column described in the utility model is dual phase filler solid-phase extraction column, be can satisfy using two class fillers
The demand that sample is handled.
2, sieve plate is arranged among tube body and is separated two class fillers for the extraction column, and filler is loose condition (of surface), and is passed through
The push rod at both ends realizes being sufficiently mixed and contacting for liquid and filler, so that the contact area of liquid and filler increases, connects
The touching time greatly shortens, so that the adsorption efficiency and eluent that improve raw material catalogue and filler be to the elution efficiency of object,
And then the Solid Phase Extraction time is shortened, save the dosage of eluent；
3, loose filler state eliminates preceding processing operation of the compacting filler before use, simplifies operating process；
4, the liquid outlet of the extraction column is positioned close on one end side wall of intermediate sieve plate, and the push rod at both ends pushed to
Between, liquid can be discharged from intermediate liquid outlet.
The utility model simple structure and reasonable design, suitable for using the extraction demand of two class fillers, the extraction column is to sample
This short processing time, volume is few, to greatly improve extraction efficiency and the working efficiency of operator, therefore this reality
It is with a wide range of applications in the preceding processing operation of raw material catalogue with novel solid-phase extraction column.
