Zearalenone (ZEN) fluorescence quantitative detection test paper is based on the indirect competition method and uses high-sensitivity fluorescence immunochromatography technology to rapidly and quantitatively determine ZEN residues in feed 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 ZEN content in the sample. The lowest detection limit of ZEN is 100 μg/kg.
