Abstract
The present invention discloses a manual solid phase extraction device, which includes a screw rod and support rods which are respectively arranged on a base plate, the screw rod and the support rods pass successively through a plate body and a press plate with the diameter matched with that of the base plate, holes are distributed on the plate body, each support rod is provided with a support base, the support rods are fixedly connected with the base plate, the plate body and the support rods are in movable connection, the press plate and the screw rod are in screw connection, the press plate and the support rods are in movable connection, and the top end of the screw rod is provided with a rocking handle. By use of a screw rod driving mechanism, torque can be converted into pressure, through the porous structure of the plate body, solid phase extraction of multiple samples and multiple kinds of samples can be simultaneously performed, the single-time sample processing number can be increased, the purposes of promotion of solid phase extraction efficiency and stabilization of the flow rate through a column can be achieved, compared with the classical manual method, the stability of the flow rate in the solid phase extraction process can be significantly improved, and the manual solid phase extraction device is more labor-saving, easy to remove and replace, low in cost, easy to use and popularize, and compatible with a variety of models of solid phase extraction columns.
Description
Technical field
The present invention relates to extraction equipment.
Background technology
Solid-phase extraction column (English SolidPhaseExtractionColumn, be called for short SPEcolumn, or SolidPhaseextractionCartridges, be called for short SPEcartridges) be from chromatographic column develop a kind of for extracting, being separated, concentrated sample pretreatment device, be 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 larger; Based on the solid-phase extraction device of principle of negative pressure due to the difference of resistance between extraction column, be difficult to reach consistent by regulating single pressure valve to make multiple sample cross column flow rate, and affect comparatively greatly by the factor such as airtight, actual extraction effect is not very good; Although full-automatic sample concentrating instrument PreplincAccuVap efficiency and automaticity high, because its price is too expensive, popularity is not high.
Summary of the invention
The invention provides a kind of manual solid-phase extraction equipment having more efficiency, to realize the SPE carrying out multiple sample or several samples simultaneously.
For realizing the object of the invention, this solid-phase extraction device is characterized in that it comprises and is assemblied in 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 with hole, support bar is provided with supporting seat, be connected between support bar and supporting seat, support bar and chassis are connected, plate body is flexibly connected with between screw rod and support bar, pressing plate and screw rod spin, be flexibly connected between pressing plate with support bar, be flexibly connected between chassis with screw rod, screw tip assembling rocking handle.
the technological progress that the present invention obtains:
Because the present invention adopts screw drive mechanism, torsion can be turned to pressure, and by the loose structure on plate body, carry out the SPE of multiple sample or several samples simultaneously, the process quantity of single sample can be improved, achieve the object promoting SPE efficiency and stablized column flow rate, compared to classical manual methods, significantly can promote the degree of stability of flow velocity in solid phase extraction procedure, and it is more laborsaving, be easy to dismounting and change, cheap, be easy to popularization and application and can the solid-phase extraction column of compatible Multiple Type.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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 comprises and is assemblied in the One On The Chassis center bolt 2 of a circular lucite and three metallic support rod 6 respectively, three metallic support rod 6 are along screw rod 2 distribution in equilateral triangle, be 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, plate body 5 is distributed with 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 for supporting organic glass plate body 5, be connected between support bar 6 and supporting seat 3, plate body 5 is flexibly connected with between screw rod 2 and support bar 6, spin between pressing plate 8 and screw rod 2, be flexibly connected between pressing plate 8 with support bar 6, be flexibly connected by being assemblied in the One On The Chassis bearing between chassis 1 with screw rod 2, wind 7 is equipped with 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 adapter 10 of dimension is good with activation rinse, solid-phase extraction column 11 is inserted circular hole 4 internal fixtion on plate body 5, uniform rotation rocking handle 7, pressing plate 8 is moved 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 reduce operation easier, and enable sample with closer to state at the uniform velocity by solid-phase extraction column 11, under the condition meeting requirement of experiment, achieve Multi-example and carry out SPE simultaneously.
