[0002] The sample filtration device for detecting pesticide residues in agricultural products is based on the rapid development of agriculture. The development of agricultural industrialization has made the production of agricultural products increasingly dependent on exogenous substances such as pesticides, antibiotics and hormones. The use of pesticides in agricultural products in my country remains high, and the irrational use of these substances will inevitably lead to excessive pesticide residues in agricultural products, affecting consumer food safety. In severe cases, it will cause consumers to become ill, have abnormal development, or even directly lead to poisoning and death. Excessive pesticide residues will also affect the trade of agricultural products. Countries around the world attach great importance to the problem of pesticide residues and have set increasingly stringent limit standards for pesticide residues in various agricultural and sideline products, posing severe challenges to China's agricultural product exports. Therefore, a sample filtration device for detecting pesticide residues in agricultural products is very necessary.
