What is the penconazole colloidal gold rapid test card?

In modern agricultural production, as a highly effective fungicide, penoxazole is widely used in disease prevention and control of crops such as fruits and vegetables. However, its excessive or improper use may lead to excessive residues in agricultural products, threatening consumer health. For the rapid and accurate detection of penoxazole residues in food, the penoxazole colloidal gold rapid detection card came into being and has become an important tool in the field of food safety detection.

In simple terms, the penoxazole colloidal gold rapid detection card is a rapid detection product based on colloidal gold immunochromatography technology. Its core principle is to use the antigen-antibody specific binding reaction to determine whether the sample contains penoxazole and the residual amount through the competitive binding detection line between the colloidal gold-labeled antibody and the penoxazole residue in the sample. The whole detection process does not require complicated equipment, just drop the sample treatment liquid into the detection card and add the sample hole, wait 10-15 minutes, and the result can be obtained by observing the color development of the detection line. The operation is simple, and ordinary personnel can master it after simple training.

Compared with traditional detection methods such as high-performance liquid chromatography and gas chromatography, the penconazole colloidal gold rapid detection card has significant advantages. The first is the speed, from the sample pre-processing to the results of only about 20 minutes, greatly reducing the detection time; secondly, the cost is low, without expensive equipment and professional operators, suitable for grass-roots regulatory departments, enterprises and field rapid screening; secondly, the sensitivity is high, can reach the ppb level detection limit, can effectively identify low concentration residues; finally, the portability is strong, the detection card is small in size, can be used on site, to meet the needs of immediate detection.

In practical applications, the penconazole colloidal gold rapid detection card is widely used in the acquisition process of agricultural production bases, the acceptance of raw materials in food processing enterprises, and the rapid sampling inspection of market supervision departments. Through rapid screening of fruits, vegetables, grains and other samples, products with excessive penconazole residues can be found in time to avoid unqualified food from entering the market, and build the first line of defense for ensuring food safety.

In short, the penconazole colloidal gold rapid detection card plays an irreplaceable role in food safety testing by virtue of its fast, simple and efficient characteristics. It is an important technical support for guarding the public's "safety on the tip of the tongue".
