Chloramphenicol Colloidal Gold Rapid Detection Card is a commonly used rapid screening tool in the field of food safety detection, mainly used to detect the residue of chloramphenicol in food. It is based on colloidal gold immunochromatography technology, which labels chloramphenicol antibodies on colloidal gold particles, and realizes qualitative or semi-quantitative detection of target substances through specific chromatographic reactions.

From the principle point of view, the core of this detection card is the specific binding reaction of antigens and antibodies. When the chloramphenicol in the sample (such as meat, aquatic products, dairy products, etc.) meets the antibody of the colloidal gold mark in the detection card, if there is chloramphenicol in the sample, it will compete with the labeled antibody to bind the chloramphenicol antigen on the detection line, resulting in a color change in the detection line; if there is no chloramphenicol The whole process usually only takes a few minutes, without complex instruments, and can be preliminarily judged by observing the results with the naked eye.

As a representative of rapid detection technology, it has remarkable characteristics: first, it is fast, the detection time is short, and it can meet the needs of on-site rapid screening; second, it is easy to operate, no professional training is required, and ordinary personnel can complete it according to the instructions; third, the cost is lower, and the cost of equipment and reagents is easier to control than traditional instrumental analysis methods (such as high performance liquid chromatography, etc.); fourth, the sensitivity is high, and the detection limit of μg/L level can be reached, which can effectively identify the trace chloramphenicol residues that may exist in food.

In the application scenario, the chloramphenicol colloidal gold rapid test card is widely used in the raw material acceptance, processing process monitoring of food production enterprises, and on-site sampling and screening of market supervision departments. It can help to detect foods that may have excessive chloramphenicol in time, reduce food safety risks, and provide efficient and convenient technical support for ensuring public dietary safety.
