DON (DON) fluorescence quantitative detection test paper is based on the indirect competition method and uses high-sensitivity fluorescence immunochromatography technology to quickly and quantitatively determine DON residues in feed raw material samples. The fully chromatographed test paper is tested by a fluorescence immunoanalyzer and passes the preset The standard curve automatically calculates the DON content in the sample, and the lowest detection limit of DON is 0.25mg/kg.
