Hefei pesticide residue detection device prototype passed

Recently, researchers from the Research Institute of Intelligent Machinery of the Institute of Intelligent Machinery of the Chinese Academy of Sciences, Hefei Research Institute of Materials Science and Technology, led researchers to make rapid progress in organophosphorus pesticide residue rapid detection technology and device R&D. The related instruments developed through the scientific research of Anhui Province The hospital's professional testing, testing accuracy to achieve the "maximum residual pesticides in food" (GB2763-2014) requirements, the indicators are to meet the needs of on-site rapid detection.

Under the support of the national "863" project, "Study on Key Technologies for Farmland Habitat Perception," members of the research group have carried out a lot of research work on rapid detection techniques for trace amounts of pesticide residues. The researchers reduced the disturbance of the power fluctuation of the light source through the single light source multi-path method, and introduced the embedded system and network communication module to develop a prototype of a miniaturized and rapid pesticide residue detection device. Experiments show that the device is easy to operate, reproducible, anti-interference ability, test data to achieve cloud storage, rapid detection of agricultural products on the scene, the future is expected to be applied and promoted in the industry.

In addition, the research group has also made extensive explorations in the basic technology for the detection of pesticide residues, and aims to build new types of portable pesticides through technologies such as surface-enhanced Raman spectroscopy (SERS), fiber modulation, advanced nanomaterial preparation, and weak signal processing. Raman spectroscopy system for qualitative and quantitative detection of ultra-trace pesticides.
