What is the phenthion colloidal gold rapid detection card?

In agricultural production, as a highly effective organophosphorus insecticide, phenthion is widely used to control underground pests and storage pests, which can effectively ensure crop yield. However, excessive use or improper use can lead to its residues in agricultural products, grain, and water quality, threatening human health. In order to quickly and accurately detect phenthion residues, phenthion colloidal gold rapid detection card came into being. It is one of the important tools in the field of food safety rapid detection.

phenthion colloidal gold rapid detection card is essentially a rapid detection test strip based on colloidal gold immunochromatography technology. Its core principle is to use the antibody of phenthion labeled with colloidal gold to react with the residue of phenthion in the sample on the test strip. When the sample is dropped into the sample hole of the detection card, it will move along the chromatographic strip. If there is octyl in the sample, it will bind to the antibody labeled with colloidal gold to prevent the antibody from binding to the octyl-OVA conjugate on the detection line (T line); if the residue of octyl in the sample is low or no, the antibody can bind to the T line to form a color strip. By observing the color development of the C line (quality control line) and the T line, it can quickly determine whether there is octyl residue in the sample.

This detection card is mainly suitable for rapid screening of octyl residue in agricultural products (such as vegetables, fruits, grains), water quality, soil and other samples. In practical applications, inspectors only need to take a small amount of samples (e.g. cutting some vegetable leaves, taking a certain volume of water sample), simply process them according to the instructions, and then drop them into the test card. The results can be read within 15 minutes, without the need for professional instruments and complex operations. It is especially suitable for grassroots supervision departments, enterprise self-inspection, and on-site rapid screening scenarios.

Compared with traditional detection methods (such as gas chromatography, liquid chromatography, etc.), the rapid detection card of phenthion colloidal gold has significant advantages: first, the detection speed is fast, and the detection is completed within 15 minutes, which greatly shortens the detection cycle; second, it is convenient to operate, and it can be used without professional training, which reduces the technical requirements for operators; third, the cost is low, and the cost of a single detection card is much lower than that of large-scale instruments; fourth, it is portable and small, and can be carried with you to the field, market and other sites to achieve "instant detection".

With the increase in food safety supervision and the development of rapid detection technology, the rapid detection card of phenthion colloidal gold plays an increasingly important role in ensuring the quality and safety of agricultural products and protecting public health. It not only provides efficient screening means for grass-roots supervision, but also provides convenience for enterprises to control production links and consumers to understand food safety.
