Aflatoxin B1 (AFB1) fluorescence quantitative detection test paper is based on the indirect competition method and uses high-sensitivity fluorescence immunochromatography technology to rapidly and quantitatively detect AFB1 residues in feed raw material samples. The fully chromatographed test paper is tested by a fluorescence immunoanalyzer and passes the pre-determined test. The set standard curve automatically calculates the content of AFB1 in the sample. The minimum detection limit of AFB1 is 10μg/kg.
