Abstract
The utility model discloses a thin-layer pesticide residue rapid detector. A movable-type moving plate is arranged on the lower part of the detector; a thin-layer plate with detected sample treatment solution is arranged on the moving plate; a light path system assembly and a CCD (charge coupled device) camera assembly are arranged just above the thin-layer plate; the light path system assembly and the CCD camera assembly are connected with a single chip; the single chip is further connected with the transmission mechanism of the moving plate, and a liquid crystal display screen; the CCD camera assembly is controlled by the single chip, and used for acquiring the spectrum information of the detected sample in different directions and under different wavelengths, and conveying the spectrum information to the single chip; the single chip is used for analysing the spectrum information, positioning on pesticide spots, comparing with data in the single chip to obtain the pesticide names and contents of the spots, and displaying on the liquid crystal display screen. The thin-layer pesticide residue rapid detector disclosed by the utility model has the advantage of being capable of qualitatively, quantitatively and rapidly detecting 11 pyrethroid pesticides, chlorothalonil, carbendazim, acetamiprid, imidacloprid and a part of carbamates pesticides.
Description
Technical field
The utility model relates to a kind of pesticide residue rapid detector, particularly a kind of thin layer pesticide residue rapid detector detecting according to thin-layer chromatography principle.
Background technology
The residues of pesticides problem of exceeding standard is one of emphasis of agricultural product security supervision, the fast detecting of current domestic residues of pesticides is mainly for organophosphorus and carbamate chemicals for agriculture, along with the forbidding of the high-toxic pesticides such as China's organochlorine, organophosphorus, the Monitoring Data statistics of serving popularization center according to Shanghai City agrotechnique shows, the qualification rate that vegetables agriculture residual speed in Shanghai City is surveyed remains on more than 99.99% for continuous 3 years, and speed is surveyed the effect of only having played deterrence.At present at home in vegetables actual production, organophosphorus, carbamate chemicals for agriculture reduce use in a large number, and the agricultural chemicals uses such as chrysanthemum ester class and Acetamiprid, Imidacloprid, Avermectin, Bravo, carbendazim are comparatively general, in the customary quantitatively sampling observation of Shanghai City residues of pesticides, above agricultural chemicals often has the phenomenon of exceeding standard to occur, and organophosphorus and carbamate chemicals for agriculture exceed standard and obviously reduce.And can also there is no at home at present ideal equipment for fast survey technology and the tacheometer of the common pesticides Residue Monitorings such as Acetamiprid, Imidacloprid, chrysanthemum ester class, Bravo, make the agricultural product securities such as vegetables occur that in this regard supervision is blank.
Utility model content
Technical problem to be solved in the utility model is that a kind of thin layer pesticide residue rapid detector that can detect the common pesticides such as Acetamiprid, Imidacloprid, chrysanthemum ester class, Bravo will be provided.
According to thin-layer chromatography principle, different material is under the expansion of particular fluid phase demodulation agent, and the Rf value of every kind of material is different, and spot size, shade and this material concentration of after launching, forming become certain proportionate relationship.According to this principle, the utility model adopts CCD imaging and multidirectional collection of illustrative plates scanning technique, can 11 kinds of pyrethrin pesticides of quantitative and qualitative analysis fast detecting, as decis, fenvalerate, cis fenvalerate, Fenpropathrin, flucythrinate, lambda-cyhalothrin, Biphenthrin, Permethrin, cypermethrin, cyfloxylate and taufluvalinate, Bravo, carbendazim, Acetamiprid, Imidacloprid and part carbamate chemicals for agriculture.
In order to solve above technical matters, the utility model provides a kind of thin layer pesticide residue rapid detector, this tacheometer bottom is provided with a movable movable plate, this movable plate is provided with the thin layer plate that is loaded with sample treating fluid, directly over thin layer plate, be provided with light path system assembly and CCD camera assembly, light path system assembly is connected with single-chip microcomputer again with CCD camera assembly, single-chip microcomputer also with the gear train of movable plate, LCDs connects, CCD camera assembly is subject to Single-chip Controlling, obtain the figure spectrum information under sample different directions and different wave length, and be sent to single-chip microcomputer, single-chip microcomputer analysis diagram spectrum information is positioned agricultural chemicals spot, compare with the data that default in single-chip microcomputer the pesticide name and the content that draw this spot, and be shown in LCDs.
Described light path system assembly and CCD camera assembly are fixed on support, and support is fixed on shell, and power supply changeover device is also housed on support.
The gear train of described movable plate is subject to Single-chip Controlling, controls linear electric motors motion, drives the turnover of movable plate.
Superior effect of the present utility model is: 11 kinds of pyrethrin pesticides of energy quantitative and qualitative analysis fast detecting, as decis, fenvalerate, cis fenvalerate, Fenpropathrin, flucythrinate, lambda-cyhalothrin, Biphenthrin, Permethrin, cypermethrin, cyfloxylate and taufluvalinate, Bravo, carbendazim, Acetamiprid, Imidacloprid and part carbamate chemicals for agriculture, made up domestic blank.
