With a large number of toxic and hazardous substances such as pesticides, veterinary drugs widely in the field of agricultural production, leading to contamination of agricultural products, the current issue of the quality and safety of agricultural products has become the focus of world concern, the vast majority of toxic and hazardous substances are highly toxic, and after skin, respiratory and gastrointestinal absorption of other ways to enter the camera body may cause serious illness. To prevent and deal with the problem of the quality and safety of agricultural products, the most effective means is timely, accurate detection. Agricultural products but how fast, accurate and sensitive detection and monitoring, become urgent problem solved. Due to the wide variety of agricultural products, detection project involves a wide range of rapid detection methods applied to agricultural products mainly: spectroscopy, chromatography, immunoassay, chemiluminescence and biological sensing method and so on. This paper aims to explore the DY5000 simple, sensitive and rapid detection of toxic and hazardous substances and detection results of the agricultural products than. Mainly includes four aspects: 1, pesticide residues in vegetables, fruits, fast detection techniques using DY5000 rapid detection of pesticide residues sensitivity, accuracy and precision, the experimental study, the results showed that the limit of detection of the organophosphate pesticides 0.3-0.7mg/kg, carbamate pesticide detection limit up to 0.01 mg / kg, in line with comparative accuracy of quantitative detection rate was 84.6%, the standard deviation of the detection of 1.39-1.64%. Clenbuterol rapid detection technology, livestock and poultry products, DY5000 clenbuterol rapid detection sensitivity, accuracy and precision experimental results show that the detection limit of clenbuterol 0.5μg/Kg Add in the pork recovery 88.0-101.4%, the detection standard deviation of 7.50-10.26%. Food products, rapid detection of aflatoxin B1, DY5000 rapid detection of aflatoxin B1 sensitivity, accuracy and precision of experimental results show that the detection limit for aflatoxin B1 to 0.05μg / Kg, add rice recoveries were 91.8-104.3%, the standard deviation of the detection of 10.11%. Rapid detection technology for chloramphenicol and malachite green, aquatic, DY5000 on chloramphenicol and malachite green rapid detection sensitivity, accuracy and precision of experimental studies, the results show that chloramphenicol the detection limit 0.1μg/Kg, the limit of detection of malachite green for 0.05μg/Kg chloramphenicol and malachite green in grass carp in recoveries of 88.3-92.3% and 91.8-92.5%, the standard deviation of the detection 4.61-12.01%. Overall, DY-5000 multifunction rapid detection technology is fast, stable, economic and easy to operate. Has a good prospect in the field of rapid detection of agricultural products.
