Embodiment
In order to be better understood from the utility model, traveling one is entered to the utility model with reference to specific embodiments and the drawings
The description of step.
As Figure 1-3, a kind of food security examines the quantitative extraction purification device of Special sample soon, realizes food security and examines soon
Fast quantification sampling, extraction and the Purification by filtration of sample.The food security examines the quantitative extraction purification device structure of Special sample soon
On contain seven most of components, respectively upper end, the specimen cup 1 of three hatch frames of lower end and side, and on the specimen cup 1
The specimen cup lid 2 that end opening is tightly connected, the filter 3 being tightly connected with the bottom end opening of specimen cup 1, hollow cross 4, branch
Frame 5 and extract solution bottle 6.
It is mainly used in scale sample sample-adding at the upper end open of specimen cup 1, opening, pressure filtration is kept before filtering in scale sample
Before cover tightly specimen cup lid 2；The lateral opening of specimen cup 1 is connected with hollow cross 4, can UNICOM's sample extracting solution；Open the bottom of specimen cup 1
Mouth connection filter 3, keeps sealing, is opened during filtering using preceding.Wherein, the filter 3 can be using the side such as plastic packaging or aluminium envelope
Formula is sealed.
Specimen cup lid 2 can use buckle or screw socket rotatory sealing with specimen cup 1.
Filter 3 can use different filter membrane or filter core to be used as filter packing according to detection project difference.Filter 3 and sample
Product cup 1 uses simple plug-in type combination.
Hollow cross 4 is needed simultaneously as the air flue when lever of quantitative sampling, the injection channel of extract solution and pressure filtration
Possess certain intensity, can be using polymeric materials such as polypropylene PP.The hollow cross 4 is provided with graduation mark.
Support 5, using clamping or eye-splice-type combination, according to detection project difference or sample and can be carried with hollow cross 4
Take liquid proportional difference adjustment support 5 and the binding site of hollow cross 4.The overall structure very simple of support 5, it supports bottom
Face can be for planar support understructure as shown in Figure 1-2, it would however also be possible to employ domed base structure is as shown in Figure 3.
Specimen cup 1 and the extract solution bottle 6 is using the material such as polyethylene for having some strength and elasticity concurrently or gathers
Propylene etc. is made, and can contain traditional extraction liquid reagent.The bottle that the design assigns extract solution bottle 6 has certain elasticity,
To meet the use demand of rapid resilience after extruding.Extract solution bottle 6 can be rotated with hollow cross 4 using screw socket to be combined or buckle knot
Close, fixed preferably by directly sealing plug, also there is good sealing to imitate because this connection method is not only easily operated
Really.
In order to improve it is of the present utility model be tightly connected performance, so the bottom of the fixing body entrance of filter 3 and specimen cup 1
Elastic seal ring is socketed between end opening.Wherein, the material of the elastic seal ring is with anti-corrosive rubber material.
Principle of the present utility model：The extract solution bottle 6 and 1 point empty of the specimen cup of extract solution will be loaded with
Not An Zhuan the hollow cross 4 two ends, now 6 ends of extract solution bottle are contacted with testboard, and the end of the specimen cup 1 is then
It is hanging to tilt.Due to weighing the ratio of sample and extract solution it has been determined that so the hollow cross 4 and the installation of the support 5
Position has also been predefined, and now only needs to add sample to be extracted into the empty specimen cup 1, until the specimen cup 1
Contacted with the testboard and extract solution bottle 6 vacantly tilt to complete the weighing operation of sample.
The extract solution is set to flow into the sample quickly through the hollow cross 4 by extruding the extract solution bottle 6 afterwards
Extraction operation is carried out in product cup 1.Again by extract solution bottle 6 extruding repeatedly with reach concussion extract, the mesh of pressure filtration
's.Wherein, the extract solution bottle 6 is the Packaging Bottle of extract solution, and this is designed as batch weighing sampling and provided a great convenience, and makes
Sampling efficiency is obtained to be obviously improved.
The utility model detects that the concrete application of sample treatment is as follows in Pesticide Residues in Vegetables：
Using the residues of pesticides in enzymatic reagent method or paper disk method detection vegetables, it is necessary to quantitatively weigh 5 grams of vegetable samples, then add
Pure water 10ml, shakes standing after 50 times and takes supernatant to detect in 10 minutes.Need to use electronic scale, sample using traditional processing mode
Product cup, vortex concussion instrument, pure water etc., extract solution clarification is waited while needing to stand, and required article is more, processing latency
It is longer.Using can quickly complete the quantitative sampling of sample in several minutes after the special quantitative sampling purifier of the utility model, carry
Take and purify, and substantially without other extras, simplify program, reduce the number of articles that outgoing Site Detection is carried,
The efficiency that the scene of substantially increasing is examined soon.
As can be seen here, this food security of the effect of this patent is examined the quantitative extraction purification device of Special sample and can not had at the scene soon
Realize that fast quantification sampling, the concussion of sample are extracted, added in the case of having electronic balance, concussion instrument, funnel, filter paper, vavuum pump
The sample pretreatment process such as press filtration purifying, simplify the flow of sample extraction purifying, save the sample extraction time and artificial,
Substantially increase the pre-treatment efficiency of fast sample product.
Embodiment of the present utility model is described in detail above, but the content is only of the present utility model preferable
Embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.All impartial changes made according to the utility model scope
Change and improvement etc., all should still be belonged within this patent covering scope.
