Pesticides are inevitably used in the agricultural production process, which has some side effects on both humans and animals, and has great destructive effects on the environment and soil. The problem of pesticide residues on fruits and vegetables has also been long-standing.
This has become an important factor hindering the development of China's fruit and vegetable industry, so it is of great significance to improve the quality and safety level of fruits and vegetables and promote the development of the fruit and vegetable industry. The veterinary drug residue detector is widely used today and is also a very useful detection instrument. It can quickly detect pesticide residues in samples and is used for the detection of organophosphorus and carbamate pesticide residues in vegetables, fruits, grains, tea, and soil.
The veterinary drug residue detector adopts the enzyme inhibition rate method, which can determine the residual levels of organophosphorus and carbamate pesticides in fruits, vegetables, and tea. The principle is based on enzymatic reaction kinetics. If the tested sample contains organophosphorus or carbamate pesticides, it will inhibit the activity of cholinesterase, affecting the reaction rate of the colorimetric system. The pesticide residue in the tested sample (inhibition rate) can be measured by measuring the rate of change in absorbance of the colorimetric system over time.
