Description
Technical field
The present invention relates to the Detection Technologies of Pesticide Residues field, a kind of especially Rapid pesticide residue detection device.
Background technology
The exceeded acute poisoning event of a lot of garden stuff pesticide residues will occur every year for China, to the country and people's property and be good for
Health causes very big harm and loss.
The conventional detection method of persticide residue is chromatography and ELISA and inhibiting AChE, and chromatography equipment is held high
Expensive, time length is high to personnel specialty level requirement；ELISA is relatively easy, but is also required to professional, analytical instrument
It is of a relatively high with technical requirements, it is cumbersome；Inhibiting AChE is easy to operate, quickly, but because poor specificity, false positive rate
The reasons such as height limit its application.Therefore a set of simplicity is established, quickly, is accurately adapted to each intermediate links of agricultural byproducts and family
The portable detecting device of front yard personal use, it is badly in need of being resolved.
Colloidal gold method be after radiation element, enzyme, fluorescein labelling technique latter novel practical labelling technique.Based on glue
The test strips of body gold immunochromatography technique are convenient with its, quickly, simple to operate, as a result high specificity, accurate and much closed
Note.
The content of the invention
In order to solve the above-mentioned technical problem, the invention provides one kind to be directed to residues of pesticides（Such as：Classes of herbicides（Bromacil,
Simanex etc.）, insecticide（Ant worm woods etc.）, bactericide class（Bravo, benomyl etc.））The collaurum of residues of pesticides is quickly examined
Device is surveyed, the sample extraction without specialty can facilitate, and quickly, disposably measure sample one or more pesticide residue.
The technical solution adopted for the present invention to solve the technical problems is：
A kind of Rapid pesticide residue detection device, including lid, box body, cassette bottom three parts；Wherein lid lower end is fixedly connected with cone
Shape rod, box body are divided into test chamber and reagent chamber two parts by partition walls, and that is fixed in reagent chamber is provided with tapered rod fixing hole
To limit tapered rod position and be allowed to be more easily aligned the sample flow export being arranged in cassette bottom, detection is provided with test chamber
Part；Cassette bottom is provided with the sample flow export for the waterproof polyethylene film for preventing sample from flowing out, and sample flow exit lower end connects
Connect to connect one end of sample flow export and the conduit of detection part, and be provided with to filter residue in water injection through pipe mouth
Screen pack, the conduit other end are connected to test chamber detection part bottom.
Further, the detection part includes Test paper, Test paper fixed plate, Test paper lid three parts group
Into the one or more Test paper fixing grooves of setting in Test paper fixed plate, Test paper covers setting and consolidated with Test paper
Determine observation window corresponding to slot number amount.
Further, the catheter diameter is 2mm, and external diameter 2.5mm, material is plastic material.
Further, the Test paper is colloid gold test paper.
Further, the box body is transparent.
The beneficial effects of the invention are as follows：The complex process of processing sample is reduced, sample is removed into mud, directly sampled with sampler
Afterwards, reagent chamber is connected with sample beating crusher, blended, sample is smashed contacts certain time with the extracts reagent in device afterwards（5-10
Minute）Afterwards, bottle cap is firmly pushed, bottom waterproof membrane can be punctured, extract solution is contacted with detection gold label test strip and reacted, 5-
Result can be read in naked eyes within 15 minutes.
Sample pretreatment process is simply accurate, the elution of sample agriculture medicament residue is become controllable.So as to terminate traditional gold mark
Test strips sample treatment is original unordered or professional cumbersome state.
The present invention is for the first time by classes of herbicides in food safety detection（Bromacil, Simanex etc.）, insecticide（Ant worm woods
Deng）, bactericide class（Bravo, benomyl etc.）One or more kinds of residues of pesticides can be detected simultaneously in a detection means
Thing, easily and fast, expand the scope of application of colloidal gold strip.
Small volume of the present invention, easy to carry, simple to operate, the scope of application is wide, can complete to detect without professional training, fits
Front yard is tested oneself of the whole family or the layman such as the market of farm produce detects and used.
