Description
Technical field
The utility model relates to chemical experiment fixture technology field, in particular to a kind of Solid Phase Extraction boost motor.
Background technique
In chemical analysis field, solid-phase extraction device is the important purification of one kind, concentration tool, including is solid-phase extraction column
Support is provided, and crosses the hyperbaric environment that column process needs and is then completed by other vacuum pump.Vacuum pump passes through pipeline and solid phase
Extraction equipment connection when cannot rely on gravity and dripping naturally, then needs to open vacuum pump, and then generation when SPE column blocks
Negative pressure provides thrust for liquid drippage in SPE column.
However, vacuum pump is expensive, and pressure is difficult to accurately control in operational process, and it is quick to even result in liquid moment
Outflow, is not able to satisfy SPE pillar to the beachhead demand (< 2 drops/sec) of sample.Therefore, it is necessary in view of the above problems, design one
It is kind low in cost and can real-time monitoring Solid Phase Extraction boost motor.
Summary of the invention
The technical problem to be solved by the utility model is to provide one kind can batch complete, and can real-time monitoring solid phase extraction
Take boost motor.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of Solid Phase Extraction boost motor, including
One air syringe, several be sequentially connected in series connection tee pipe coupling and several with the tee pipe coupling one by one
The corresponding column cap for being used cooperatively with solid phase extraction column is coaxially arranged with spiral shell on the syringe needle of the air syringe
The air inlet of bolt, tee pipe coupling described in the bolt and front end is connected by thread seal, tee tube described in end
The gas outlet of connector is provided with sealing plug, the master of the gas outlet of the air syringe and each tee pipe coupling
Pipe is connected to form vent stack road, and the branch pipe of each tee pipe coupling passes through snorkel and the corresponding column cap
Connection forms vent branch road, is provided in the column cap for being connected to the snorkel and the solid phase extraction column
Venthole.
The syringe needle end of the air syringe is provided with for preventing the bolt to be detached from the air 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 snorkel is arranged with T-type upper cover, the T-type upper cover and the T joint
The branch pipe gas outlet of head is connected by thread seal；The lower end outer wall of the snorkel is arranged with T-type lower head, the T
Type lower head is connect with the venthole of the column cap 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 boostings
Device unscrews sealing plug in use, column cap is connect with solid phase extraction column one by one, and after syringe is filled gas, cooperation is screwed
Sealing is formed afterwards, gas is pressed into end SPE pillar, pressurization dynamics tested liquid drop speed is adjusted in real time.By this boost motor,
Laboratory cost, while manual boosting is greatly saved, more preferably meets SPE pillar to the beachhead demand (< 2 drops/sec) of sample,
Make testing result more accurate and effective.

4, it is coaxially arranged with bolt 5 on the syringe needle of air syringe 1, the air inlet of bolt 5 and front end tee pipe coupling 2 is close by screw thread
Envelope connection, the gas outlet of end tee pipe coupling 2 are provided with sealing plug 6, the gas outlet of air syringe 1 and each tee tube
The supervisor of connector 2 is connected to form vent stack road, and the branch pipe of each tee pipe coupling 2 passes through snorkel 7 and is connected to shape with column cap 4
At vent branch road, it is provided in column cap 4 and divides snorkel 7 and the venthole of solid phase extraction column 3 (not to show in figure for being connected to
Show).
In this particular embodiment, as shown in Figure 1, the syringe needle end of air syringe 1 is provided with for preventing bolt 5 de-
The stopper 8 of syringe needle from air syringe 1, stopper 8 are the diameter that truncated cone-shaped and its maximum gauge are less than bolt 5.Snorkel 5
Upper end outer wall is arranged with T-type upper cover 9, and T-type upper cover 9 is connect with the branch pipe gas outlet of tee pipe coupling 2 by thread seal；
The lower end outer wall of snorkel 5 is arranged with T-type lower head 10, and the venthole of T-type lower head 10 and column cap 4 passes through thread seal company
