Product introduction
      Aflatoxin B1 (AFB1) is a highly toxic substance, which has strong toxicity and carcinogenicity to human and animals. It mainly pollutes peanut, corn, rice, wheat, peanut oil and other cereals and oils, which is one of the necessary inspection items for most foods.

1. Kit description
      This product is a colloidal gold rapid detection card for aflatoxin B1, which is used for quantitative detection of aflatoxin B1 residues in grain and its products, and meets the national limit standard for aflatoxin B1 in pollutants.

2. Principle of kit
      This method is based on competitive colloidal gold technology. Two invisible lines are sprayed on the central white film surface of the detection card. The top one is the quality control line C, and the bottom one is the detection line t; If the sample does not contain aflatoxin B1, most of the aflatoxin B1 antibody colloidal gold complexes on the reaction card will be captured by the T-line, and the T-line will be obvious. If the sample contains aflatoxin B1, the color of T-line will be lighter with the increase of aflatoxin B1 concentration. The content of aflatoxin B1 was determined by measuring the absorbance value of T-line.

3. Detection range
      Quantitative determination of aflatoxin B1 in grain and its products.
      Detection range: 2-150 μ g/kg(ppb)

4. Technical parameters
