Description
Technical field
It the utility model is related to a kind of solid-phase micro-extracting device.
Background technology
Traditional fiber head SPME is will to scribble the quartz fibre probe insertion of fixer or deposition adsorbent
Into sample substrate to be measured, sorption extraction and assigning process are completed.Its weak point：Probe sorption extraction sample size has
Limit, conventional efficient are low.
Utility model content
It is more that the purpose of this utility model is to provide a kind of extraction sample size, the high micro- extraction of multifilament head solid phase of conventional efficient
Take device.
The utility model mainly includes handle, branch sleeve, fixes sleeve, spring, fix bar, fiber head and slip cap
Cylinder.
Wherein, branch sleeve is fixedly connected with the lower end of handle, branch sleeve is the cylindrical housings of upper and lower opening, even
The outer wall of female connector cylinder is provided with some axial bar through holes.Be provided with fixes sleeve in the inside of branch sleeve, fixes sleeve it is upper
End is connected with the lower end of handle, and some fix bars, each fix bar and branch sleeve are flexibly connected on the outer wall of fixes sleeve
On strip through-hole it is mutually corresponding successively.Spring is fixedly connected with the outer wall of fixes sleeve, one end of each spring is with consolidating
Determine sleeve to be connected, the other end is connected with fix bar respectively, and fiber head is provided with the lower end of fix bar.In the outer cover of branch sleeve
Sliding sleeve is connect, sliding sleeve is the cylindrical housings of upper and lower opening.The upper end of handle, at its lower end and branch sleeve strip through-hole it
Between distance, more than the height of sliding sleeve.
When in use, sliding sleeve is enclosed on the outside of branch sleeve to the utility model, makes spring-compressed, and fix bar, which is in, hangs down
Straight state.Upward sliding sliding sleeve, under the action of the spring, fix bar open, and start to extract.
The utility model has the following advantages that compared with prior art：
1. relative to solid phase extraction techniques, multifilament head SPME overcomes the sky occurred when using original technology
White value is high, easy the defects of blocking adsorption column；Advantage is that multigroup testing sample can be determined simultaneously, overcomes traditional fibre head solid phase
Micro-extraction data sheet one in measure, it is impossible to the shortcomings that surveying parallel laboratory test data.
2. the quantity of solvent of liquid-liquid technique consumption is big, environment is polluted, the health of operating personnel is endangered, at this
Aspect SPME accounts for very big advantage.
3. although liquid-phase micro-extraction has the advantages that simple and quick, cost is cheap, still need consumption solvent,
But SPME realizes solvent free, extracting head is that a quartz for scribbling different chromatographic stationary phases or adsorbent is fine
Dimension, may be reused.

Embodiment
In the simplified schematic diagram of the present utility model shown in Fig. 1 and Fig. 2, branch sleeve is fixedly connected with the lower end of handle 1
2, branch sleeve is the cylindrical housings of upper and lower opening, and three axial bar through holes 3 are provided with the outer wall of branch sleeve.Even
The inside of female connector cylinder is provided with fixes sleeve 4, and the upper end of fixes sleeve is connected with the lower end of handle, living on the outer wall of fixes sleeve
Three fix bars 5 of dynamic connection, each fix bar are mutually corresponding successively with the strip through-hole on branch sleeve.In the outer of fixes sleeve
Spring 6 is fixedly connected with wall, one end of each spring is connected with fixes sleeve, and the other end is connected with fix bar respectively, solid
The lower end of fixed pole is provided with fiber head 7.In the outside socket sliding sleeve 8 of branch sleeve, sliding sleeve is the cylinder of upper and lower opening
Shape housing.The distance between upper end of handle, at its lower end and branch sleeve strip through-hole, more than the height of sliding sleeve.
