Application of High-Throughput Tissue Grinding Apparatus in Detecting Pesticide Residues
Pesticide residue detection is an important step in ensuring the safety of vegetables and other agricultural products. It is also an important measure to avoid agricultural product safety accidents. With the development of agriculture, the detection of pesticide residues becomes more and more important. At the same time, it needs to improve the speed of detection to adapt to society. The development needs, the traditional methods of pesticide residue detection in the past, time-consuming, laborious, and low efficiency in the grinding of samples, and now using high-throughput tissue grinding instrument, in 3-5min, you can complete the processing of 12 samples , greatly improve the efficiency, reduce errors, and the processing method is tested in full compliance with the requirements of the relevant national standards.
High-throughput tissue grinders use vertical oscillations to collide the frozen sample in the grinding tube with the grinding ball model. The resulting shear force and impact force completely break the tissue. Its use in pesticide residue detection is mainly used in the pretreatment of pesticide residue testing samples, that is, as a tool for sample grinding. In pesticide residue testing, this step is commonly used in the sample crushing process. The measured sample was weighed briefly and placed in a 50 ml centrifuge tube. Then 10 ml of acetonitrile extract was added. Two 15 mm beads were ground and ground at 1000 r/min for 3 min on a high-throughput tissue grinder. A preliminary pesticide residue test sample is obtained. After the extraction liquid is separated, the salt water is removed, and the adsorbent is decontaminated, a clear liquid can be obtained for further detection and analysis.
The application of high-flux tissue grinders in pesticide residues detection is a very important technology application in modern pesticide residue detection, especially in the experimental process of accurately determining various components in pesticide residues. The use of a high-throughput tissue grinder for smashing the sample to be tested can effectively increase the speed of crushing and ensure the effect of crushing, which in turn drastically shortens the cycle and time for the detection of pesticide residues. This can be used to analyze the causes of pesticide residues and to trace pesticides. Disadvantages provide timely, effective and accurate data, ensuring food safety at the tip of the tongue.
