And complete the purification and concentration of determinand.
Solid-phase extraction device can generally place 20-30 solid-phase extraction column, and the sample institute of same batch processed simultaneously
What is used is all the solid-phase extraction column of same specification, and step divides equally are as follows: activation, balance, loading, elution, elution, in above-mentioned 5 step,
In addition to loading need individually one by one complete other than, other four steps can batch operation, be completed at the same time.It is above-mentioned however in traditional operation
Five steps pass through manually liquid feeding one by one and complete, time-consuming and laborious.In commercialization analysis detection laboratory, detection portfolio increasingly increases
Greatly, when encountering the detection process for needing solid-phase extraction column, such device seriously restricts detection cycle.Therefore, design one is needed
Kind can batch complete activation, balance, elution, elution, operate convenient and fast Solid Phase Extraction charger.
Summary of the invention
The technical problem to be solved by the utility model is to provide one kind can batch complete activation, balance, elution, elution,
Operate convenient and fast Solid Phase Extraction charger.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of Solid Phase Extraction charger, including
One sample liquid syringe, several be sequentially connected in series connection tee pipe coupling and several with the tee pipe coupling one by one
Corresponding branch's injection tube, is coaxially arranged with bolt on the syringe needle of the sample liquid syringe, described in the bolt and front end
The import of tee pipe coupling connected by thread seal, the outlet closing of tee pipe coupling described in end, the sample liquid
The liquid outlet of syringe is connected to form infusion primary path with the supervisor of each tee pipe coupling, each tee tube
The branch pipe of connector passes through pipeline and is connected to form infusion forehearth limb with corresponding branch's injection tube, branch's injection
It is provided with venthole on cylinder and at its inlet, the liquid outlet of branch's injection tube is provided with and solid phase extraction column
The column cap being used cooperatively is provided in the column cap for being connected to branch's injection tube and the solid phase extraction column
Through-hole.
The syringe needle end of the sample liquid syringe is provided with for preventing the bolt to be detached from the sample liquid injection
The stopper of the syringe needle of device, the stopper are the diameter that truncated cone-shaped and its maximum gauge are less than the bolt.
The upper end outer wall of the pipeline is arranged with T-type upper cover, the T-type upper cover and the tee pipe coupling
Branch outlet pass through thread seal connect；The lower end outer wall of the pipeline is arranged with T-type lower head, seals under the T-type
Head is connect with the inlet of branch's injection tube by thread seal.
The column cap is the descending multilayer coaxial clyinder successively to successively decrease of diameter from top to bottom.It can be with different size
The solid phase extraction column of type matches.
Compared with the prior art, the advantages of the utility model are: the utility model discloses a kind of Solid Phase Extraction liquid feedings
Device unscrews bolt at syringe needle and removes syringe, be filled liquid back spin in use, column cap is connect with solid phase extraction column one by one
Tight bolt injects liquid into branch's injection tube, since branch's injection tube is equipped with venthole, is left a blank to liquid by gravity
Afterwards, next step operation is carried out, the activation of SPE column is sequentially completed, is balanced, elution and elution.By this charger, can single step it is complete
At the activation of all SPE columns of same batch, balance, the operation of elution and elution is suitble to the batch operation of large size assay laboratory, fastly
It is prompt efficient.
