What is the triazophos colloidal gold rapid detection card?

Triazophos is a widely used organophosphorus insecticide, which is commonly used to control pests on crops such as cotton, rice, and fruit trees. However, if triazophos residues in food exceed the standard, it will pose potential threats to human health, such as nervous system damage, endocrine disruption, etc. Therefore, it is essential to quickly and accurately detect triazophos residues in food. Triazophos Colloidal Gold Rapid Detection Card, it is based on this demand that an efficient detection tool came into being.

By definition, Triazophos Colloidal Gold Rapid Detection Card is a rapid detection test strip using colloidal gold immunochromatography technology. The core principle is to use the specific binding reaction of antigens and antibodies. When the triazophos in the sample binds to the antibody labeled with colloidal gold, a specific color-developing band will be formed on the test strip. The presence or depth of the band can quickly determine the residue of triazophos in the sample.

In practical applications, the detection card is extremely simple to operate. Just drop the sample (such as the extract of vegetables, fruits, or the soaking liquid of grains) into the sample hole of the detection card and wait for 10-15 minutes to observe the results. If both the detection line (T line) and the quality control line (C line) are colored, it indicates that the triazophos in the sample is not detected or the residue is lower than the detection limit; if only the quality control line is colored, it indicates that the triazophos residue in the sample exceeds the standard.

Compared with traditional detection methods (such as gas chromatography, liquid chromatography, etc.), the triazophos colloidal gold rapid detection card has significant advantages: first, the detection speed is fast, and the results can be obtained in 10-15 minutes without the need for complex instruments and professionals; second, the operation threshold is low, and ordinary staff can master it after simple training; third, the cost is relatively low, which is suitable for large-scale rapid screening; fourth, the sensitivity is high, which can detect low-concentration triazophos residues.

At present, the test card is widely used in the raw material acceptance, processing process monitoring of food production enterprises, as well as the rapid sampling inspection of market supervision departments and the on-site screening of grass-roots detection points, which provides strong support for ensuring food safety and preventing the risk of pesticide residues.
