Abstract
The utility model discloses a simple solid-phase extraction complete device facilitating closed connection fit. The simple solid-phase extraction complete device comprises a plunger type metering cylinder (1) and a receiving tube (3), wherein the plunger type metering cylinder (1) is in closed connection with a small solid-phase extraction column (2) through a sealing joint (4); the small solid-phase extraction column (2) is in closed connection with the receiving tube (3) through the sealing joint (4). A sleeved sealed fit structure among the plunger type metering cylinder, the small solid-phase extraction column and the receiving tube is adopted, and the passing speed of an eluent through the small solid-phase extraction column is controlled by a piston; meanwhile, contact between a person and an organic reagent is reduced. The simple solid-phase extraction complete device is simple in structure, easy to operate and low in manufacturing cost, and is particularly suitable for being used in a small laboratory; the simplicity of connection fit is improved; complete connection fit between a solid-phase extraction device and an accessory thereof is facilitated.
Description
Technical field
The utility model belongs to the laboratory with experiment utensil technical field, is specifically related to a kind of simple in structurely, easy and simple to handle, connects the firm simple and easy SPE complexes that are easy to airtight connection cooperation.
Background technology
SPE (Solid-Phase Extraction, be called for short SPE) be developed recently a kind of sample pretreatment technology of getting up, by the development that combines of liquid-solid extraction and column liquid chromatographic technology, be mainly used in separation, the purifying and concentrated of sample, compare with traditional liquid-liquid extraction method and can improve the rate of recovery of analyte, more effectively analyte is separated with interfering component, reduces the sample pretreatment process, simple to operate, save time, laborsaving.Solid phase extraction techniques development at present is very fast, but major part is expensive automation solid-phase extraction device, the general unable outfit in small test chamber.Existing homemade solid-phase extraction device mainly is made of solid phase extraction column and auxiliary, but there is complex structure, complex operation, uncontrollable eluent flow rate cause defectives such as stand-by period length, sample purification weak effect and the rate of recovery are low, influence the effect that solid phase is separated.For this reason, develop a kind of simple in structurely, easy and simple to handle, the speed of control eluent by pillar reduces the people and seems with the solid-phase extraction device that contacts of organic reagent and be necessary very much.
The utility model content
It is a kind of simple in structure, easy and simple to handle that the purpose of this utility model is to provide, and cost of manufacture is cheap, is easy to the simple and easy SPE complexes that airtight connection cooperates.
The purpose of this utility model is achieved in that and comprises plunger type hopper and receiving tube, and described plunger type hopper is connected by seal nipple and solid phase extraction column are airtight, and described solid phase extraction column is connected by seal nipple and receiving tube are airtight.
The utility model adopts between plunger type hopper, solid phase extraction column and the receiving tube socket structure that is sealed and matched, and by the speed of piston control eluent by the extraction pillar, simultaneously, reduces contacting of people and organic reagent.The utility model is simple in structure, and is easy and simple to handle, and cost of manufacture is cheap, improved to connect the simplicity that cooperates, and the complete property connection that is conducive to solid-phase extraction device and annex thereof cooperates, and especially is appropriate to the indoor use of small test.
Description of drawings

Among the figure: 1-plunger type hopper, 2-solid phase extraction column, 3-receiving tube, 4-seal nipple, 41-sealing strip, 42-gas pressure relief slot, 5-piston.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, but never in any form the utility model is limited, any conversion based on the utility model training centre is done all falls into protection domain of the present utility model.
Shown in Fig. 1 ~ 2, the utility model comprises plunger type hopper 1 and receiving tube 3, and described plunger type hopper 1 is by seal nipple 4 and 2 airtight connections of solid phase extraction column, and described solid phase extraction column 2 is by seal nipple 4 and 3 airtight connections of receiving tube.
Described plunger type hopper 1 cooperates with piston 5 socket joint type work.
On the described seal nipple 4 sealing strip 41 is set.
On the described seal nipple 4 gas pressure relief slot 42 is set.
Described gas pressure relief slot 42 is distributed in around the seal nipple 4.
Described seal nipple 4 middle parts arrange the rotation urging structure.
The liqiud outlet head of described plunger type hopper 1 and seal nipple 4 socket tight fits.
Described solid phase extraction column 2 cooperates with seal nipple 4 sockets.
Described receiving tube 3 cooperates with seal nipple 4 sockets.
The utility model operation principle and the course of work:
The utility model adopts between plunger type hopper, solid phase extraction column and the receiving tube socket structure that is sealed and matched, and by the speed of piston control eluent by the extraction pillar, simultaneously, reduces contacting of people and organic reagent.
During work, at first take out piston, add a certain amount of eluent in the plunger type hopper, piston is packed in the plunger type hopper, strength with appropriateness pushes away plunger type hopper piston, make eluent flow through solid phase extraction column with certain speed, solid phase extraction column is activated, liquid is collected in the receiving tube; Then, take out above-mentioned receiving tube, change another receiving tube again and connect solid-phase extraction column with seal nipple, connection can not be too tight; Take out piston, add a certain amount of eluent in the plunger type hopper, again piston is packed in the plunger type hopper, push away plunger type hopper piston with the strength of appropriateness, automatically flow in the receiving tube after making eluent flow through solid phase extraction column with certain speed, finish extraction process.
