Description
Technical field
The utility model relates to a kind of drawing-in type impurity absorption pattern SPE column device.
Background technology
At present, agricultural product, feed and the multicomponent such as Pesticide and mycotoxin residue detection adopt impurity absorption pattern to carry out purified treatment to sample extracting solution usually.General way is, is first placed in plastic centrifuge tube by impurity absorption material and preserves.During use, then appropriate amount of sample extract is joined in centrifuge tube to vibrate with impurity absorption material and mix, then centrifugation scavenging material, then pipette supernatant, complete purification process.But there are 2 problems in this method.One is that operating process is relatively loaded down with trivial details, needs the equipment that turbula shaker, centrifuge etc. are supporting; Two is because the density of some sorbing materials own is light, particle is little, then is easy to enter in scavenging solution when pipetting supernatant, thus brings adverse effect to ensuing analysis detection.
Utility model content
The purpose of this utility model is to provide a kind of drawing-in type impurity absorption pattern SPE column device, the utility model can without the need under the condition of auxiliary equipment, complete rapidly sample extracting solution purification process, effectively prevent sorbing material to be mixed into scavenging solution, overcome existing impurity absorption pattern purification method and there is complex operation, need special equipment and sorbing material and scavenging solution to be difficult to the deficiency be separated completely.
Drawing-in type impurity absorption pattern SPE column device provided by the utility model, comprises a column jecket;
One end of described column jecket is communicated with a syringe needle, and nearly described needle end, be provided with upper sieve plate and lower sieve plate in described column jecket, between described upper sieve plate and described lower sieve plate, be filled with filler;
Be provided with the piston that can move along its axis in described column jecket and be attached thereto the piston rod connect;
The sidewall of described column jecket is communicated with the drain pipe that can close setting.
In described SPE column device, be vertical setting between described drain pipe with described column jecket, contribute to the discharge of scavenging solution.
In described SPE column device, described drain pipe is sealed by a plug, when needing to discharge scavenging solution by described drain pipe, removes described plug.
In described SPE column device, described upper sieve plate and be interference fit between described lower sieve plate and described column jecket, thus fix described upper sieve plate, described lower sieve plate and described filler by this over pressure.
In described SPE column device, the aperture of described upper sieve plate and described lower sieve plate is all less than the particle diameter of described filler, in order to avoid described filler oozes out.
The utility model drawing-in type impurity absorption pattern SPE column device has following beneficial effect:
The utility model does not need necessary instrument equipment, purification and the scavenging solution separation process of impurity absorption pattern in agricultural product and Safety of Food Quality detection is completed by means of only a simple mechanism, easy to operate, quick, and effectively prevent sorbing material and be mixed into scavenging solution.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model drawing-in type impurity absorption pattern SPE column device.
In figure, each mark is as follows:
1 piston rod, 2 column jeckets, 3 pistons, 4 upper sieve plates, 5 fillers, 6 times sieve plates, 7 syringe needles, 8 sheaths, 9 drain pipes, 10 plugs.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further, but the utility model is not limited to following examples.
As shown in Figure 1, be the structural representation of the utility model drawing-in type impurity absorption pattern SPE column device, it comprises a high purity polypropylene material column jecket 2, and one end of column jecket 2 is communicated with a syringe needle 7, and when not using, this syringe needle 7 sheath 8 entangles.Near syringe needle 7 end is set, the upper sieve plate 4 of high-molecular polythene material and the lower sieve plate 6 of high-molecular polythene material is provided with in column jecket 2, and between upper sieve plate 4 and lower sieve plate 6, be filled with the filler 5 of high-purity ball-type end-blocking C18 and CNT mixing, its aperture is greater than the aperture of upper sieve plate 4 and lower sieve plate 6, in order to avoid it oozes out from upper sieve plate 4 and lower sieve plate 6.In the utility model, upper sieve plate 4 be ensured and be interference fit between lower sieve plate 6 and column jecket 2, thus rely on this over pressure to firmly fix sieve plate 4, lower sieve plate 6 and filler 7.In column jecket 2, be provided with the piston 3 that can move along its axis and be attached thereto the piston rod 1 connect, from extract, extracting scavenging solution by the mating reaction of piston 3 and piston rod 1.The utility model is communicated with a drain pipe 9 on the sidewall of column jecket 2, and it is vertical setting with column jecket 2, contributes to the discharge of scavenging solution, and its liquid outlet end coordinates a plug 10, to seal this drain pipe 9.
When using the utility model drawing-in type impurity absorption pattern SPE column device, can carry out in accordance with the following steps:
First the sheath 8 of syringe needle 7 is extractd during use, then syringe needle 7 is vertically inserted in sample extracting solution to be clean, pull out piston rod 1 and form negative pressure sample extracting solution is entered in column jecket 2 by lower sieve plate 6, filler 5 and upper sieve plate 4, be namely purified liquid.With hand break into two with one's hands drain pipe 9 port plug 10, open fluid port, upset column jecket 2 makes the outlet end mouth down of drain pipe 9 aim at and connects liquid test tube, promote piston rod 1, scavenging solution in column jecket 2 enters adapter under malleation and Action of Gravity Field, thus reaches the object be separated with scavenging solution sample extracting solution fast purification.
