Abstract
The utility model discloses a manual solid phase extraction device, it is including assembling screw rod and the bracing piece on a chassis respectively, wears to adorn one and chassis the diameter plate body and the clamp plate that match on screw rod and bracing piece in proper order, it has the hole to distribute on the plate body, is provided with the supporting seat on the bracing piece, and the bracing piece links firmly with the chassis, swing joint between plate body and screw rod and bracing piece, and the clamp plate connects with the screw rod soon, swing joint between clamp plate and bracing piece, screw rod top assembly rocking handle. Because the utility model discloses a screw drive mechanism, can turn into pressure with torsion, and through the porous structure on the plate body, the solid -phase extraction of a plurality of samples or multiple sample carries out simultaneously, can improve the processing quantity of single sample, the mesh of having realized promoting solid -phase extraction efficiency and having stabilized the column flow rate, compare in the manual method of classics, can promote the measure of stability of the solid -phase extraction in -process velocity of flow by a wide margin, and it is more laborsaving, easily dismantle and change, low manufacture cost, easily popularization and application and solid -phase extraction post that can compatible multiple model.
Description
Technical field
The present invention relates to extraction equipment.
Background technology
Solid-phase extraction column (English SolidPhaseExtractionColumn, it is called for short SPEcolumn, or SolidPhaseextractionCartridges, it is called for short SPEcartridges) it is a kind of sample pretreatment device for extracting, separate, concentrating developed from chromatographic column, it is widely used in many GBs and industry analysis standard.
At present, in solid phase extraction procedure, it is low that classical manual method crosses column efficiency, and the flow velocity that flow velocity is difficult to reach requirement of experiment because of manual operation difference is fixed and uniformity, is difficult to be competent at for the experimental project that sample size is bigger; Based on the solid-phase extraction device of principle of negative pressure due to the difference of resistance between extraction column, being difficult to make multiple sample cross column flow rate to reach unanimously by regulating single pressure valve, and affected relatively greatly by the factor such as airtight, actual extraction effect is not very good; Although full-automatic sample concentrating instrument PreplincAccuVap efficiency and automaticity are high, but owing to its price is prohibitively expensive, popularity is not high.
Summary of the invention
The present invention provides the manual solid-phase extraction equipment of a kind of more efficiency, to realize carrying out the Solid-Phase Extraction of multiple sample or several samples simultaneously.
For realizing the object of the invention, this solid-phase extraction device is characterized in that it includes being assemblied in the screw rod on a chassis and support bar respectively, screw rod and support bar install successively one with the plate body of chassis diameter compatible and pressing plate, described plate body is distributed hole, support bar is provided with supporting seat, it is connected between support bar and supporting seat, support bar is connected with chassis, it is flexibly connected between plate body with screw rod and support bar, pressing plate and screw rod spin, it is flexibly connected between pressing plate with support bar, is flexibly connected between chassis with screw rod, screw tip assembling rocking handle.
The technological progress that the present invention obtains:
Owing to the present invention adopts screw drive mechanism, torsion can be turned to pressure, and by the loose structure on plate body, carry out the Solid-Phase Extraction of multiple sample or several samples simultaneously, the process quantity of single sample can be improved, achieve and promote Solid-Phase Extraction efficiency and stablized the purpose of column flow rate, compared to classical manual methods, can be substantially improved in solid phase extraction procedure the degree of stability of flow velocity, and it is more laborsaving, it is readily disassembled replacing, cheap, it is easy to the solid-phase extraction column of popularization and application compatible Multiple Type.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described further.
As shown in Figure 1, this solid-phase extraction device includes being assemblied in the circular the One On The Chassis center bolt 2 of lucite and three metallic support rod 6 respectively, three metallic support rod 6 are distributed along screw rod 2 in equilateral triangle, it is connected between three metallic support rod 6 and chassis 1, center bolt 2 with three metallic support rod 6 install a lucite plate body 5 identical with the diameter on chassis 1 and lucite pressing plate 8 successively, on plate body 5, distribution has multiple hole 4, hole 4 is circular hole, its pore size can set as required, each support bar 6 is provided with supporting seat 3, this supporting seat 3 is used for supporting lucite plate body 5, it is connected between support bar 6 and supporting seat 3, it is flexibly connected between plate body 5 with screw rod 2 and support bar 6, spin between pressing plate 8 and screw rod 2, it is flexibly connected between pressing plate 8 with support bar 6, pass through to be assemblied in the One On The Chassis bearing between chassis 1 with screw rod 2 to be flexibly connected, it is equipped with wind 7 on the top of screw rod 2.
The syringe 9 sucking quantitative sample solution is connected by the solid-phase extraction column 11 that the adaptor 10 of dimension is good with activation rinse, solid-phase extraction column 11 is inserted in the circular hole 4 on plate body 5 fixing, uniform rotation rocking handle 7, pressing plate 8 is made to move down, make syringe piston rod uniform descent under the compressing of pressing plate 8, due to rocking handle 7 circumferentially orbiting motion, considerably increase stroke needed for manual pressure, simultaneously because of lever principle, required active force reduces, thus reducing operation easier, and enable sample to pass through solid-phase extraction column 11 closer to state at the uniform velocity, when meeting requirement of experiment, achieve Multi-example and carry out Solid-Phase Extraction simultaneously.
