Description

Technical Field

[0001] This disclosure relates to the field of detection cards, and more particularly to a pesticide residue colloidal carbon detection card. Background Technology

[0002] The use of pesticides has greatly increased crop yields, but pesticide residues can remain in vegetables, fruits, fish, shrimp, and eggs, causing food contamination and posing a serious threat to human health. Therefore, monitoring pesticide residues in agricultural products is extremely important.

[0003] To quickly detect pesticide residues, test strips are typically used. Specifically, for example... Figure 1 As shown, the device includes a base plate 101, on which a nitrocellulose membrane 104 is mounted. Sample pads 102 and absorbent filter paper 103 are respectively mounted at both ends of the nitrocellulose membrane 104. The absorbent filter paper 103 is pressed onto the nitrocellulose membrane 104. The sample pads 102 and the nitrocellulose membrane 104 are connected by a binding pad 105. A pressure plate 106 is mounted on the upper housing 11. The pressure plate 106 presses against the connection between the nitrocellulose membrane 104 and the binding pad 105, thereby ensuring that the sample absorbed by the sample pads 102 is smoothly transferred to the nitrocellulose membrane 104. The nitrocellulose membrane 104 is used to detect pesticide residues. If the contact between the binding pad 105 and the sample pad 102, or between the binding pad 105 and the nitrocellulose membrane 104, or between the absorbent filter paper 103 and the nitrocellulose membrane 104 is poor, it can easily affect the flow of the sample, thus affecting the display of the detection results.
