Detect AFB
1method mainly contain thin-layered chromatography, high performance liquid chromatography, euzymelinked immunosorbent assay (ELISA) etc.But thin-layered chromatography complex operation, consuming time, the impact that is subject to each factor in analytic process, the accuracy of method is very poor; High performance liquid chromatography can detect multiple toxin simultaneously, and sensitivity is higher, but requires that sample purity is high, expensive equipment, is difficult to popularize; There is the shortcoming such as false positive, false negative in euzymelinked immunosorbent assay (ELISA).
Utilize AFB
1the characteristic of natural fluoresence can be sent under the irradiation of ultraviolet light, excite the fluorescence of generation to detect to it.It is fast that this detection method has speed, and can the feature of accurate quantitative analysis.Fluorescence detector is used to detect the AFB of ultramicron
1, be widely used for the highly sensitive detection method as aflatoxin.But, adopt Fluorometric assay usually to need and the method coupling such as high performance liquid chromatography, pre-treatment isolation technics.Immune affinity column method, often as the earlier stage processing method of the method, this adds increased testing cost and experimental procedure.
Summary of the invention
The purpose of this utility model is that providing a kind of reduces AFB in the on-line checkingi corn of testing cost, raising detection speed
1detector, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
AFB in a kind of on-line checkingi corn
1detector, comprise CCD, fluorescent tube, transport tape and device housings; Transport tape runs through device housings, and the device housings above transport tape is can; CCD, fluorescent tube are arranged on the top of device housings inside, and CCD is positioned at device housings top center, fluorescent tube comprises the first fluorescent tube, the second fluorescent tube, the 3rd fluorescent tube, the 4th fluorescent tube, first fluorescent tube, the second fluorescent tube, the 3rd fluorescent tube, the size of the 4th fluorescent tube, model are identical, and are distributed in the surrounding of CCD uniformly and equidistantly.
As further program of the utility model: CCD is also connected with computer.
As further program of the utility model: fluorescent tube adopts wavelength to be the uviol lamp of 365nm.
Compared with prior art, the beneficial effects of the utility model are:
AFB in on-line checkingi corn in the utility model
1detector belong to fluorescence detection, it is the AFB of direct-detection sample surfaces
1, and do not need to carry out sample the steps such as pre-treatment, greatly reduce testing cost, improve detection speed, the utility model continuously can detect the AFB in different corn simultaneously
1concentration, and do not affect other samples.
Accompanying drawing explanation

1the structural representation of detector;
In figure: 1-first fluorescent tube, 2-second fluorescent tube, 3-CCD, 4-the 3rd fluorescent tube, 5-the 4th fluorescent tube, 6-transport tape, 7-device housings.
Embodiment
Below in conjunction with the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment 1
Refer to Fig. 1, in the utility model embodiment, AFB in a kind of on-line checkingi corn
1detector, comprise CCD3, fluorescent tube, transport tape 6 and device housings 7.Transport tape 6 runs through device housings 7, and the device housings 7 above transport tape 6 is can.CCD3, fluorescent tube are arranged on the top of device housings 7 inside, and CCD3 is positioned at device housings 7 top center, fluorescent tube comprises the first fluorescent tube 1, second fluorescent tube 2, the 3rd fluorescent tube 4, the 4th fluorescent tube 5, first fluorescent tube 1, second fluorescent tube 2, the 3rd fluorescent tube 4, the 4th fluorescent tube 5 size, model are identical, and are distributed in the surrounding of CCD3 uniformly and equidistantly.Fluorescent tube adopts wavelength to be the uviol lamp of 365nm.CCD3 is also connected with computer.
Above-mentioned detector is used for AFB in on-line checkingi corn
1detection method, concrete steps are as described below:
1. transport tape 6 drives corn to be measured average rate from device housings 7 to flow through, and has AFB in corn
1part can send blue-green fluorescent under ultra violet lamp, the power (light intensity) of fluorescence has reacted the number of aflatoxin B1 concentration, light intensity and concentration correlation.
2. by the corn sample of variable concentrations, gather relevant data image signal by CCD3, computer reads fluorescent value in analysing digital image signal and and AFB
1concentration sets up linear relationship curve.
3. on high speed high definition CCD3 continuous acquisition transport tape 6 corn data image signal and transfer on computer, pass through AFB
