Abstract：Eel (A nguilla anguilla) was bathed in malachite green at certain concentration to make the malachite green enter the eel and contain leucomalachite green (LMG) in muscle via metabolism to estab‐lish a method for the preparation and certification of the reference material of leucomalachite green (LMG) residues in the muscle .The positive 500 bags of samples of eel were performed in one batch by the proce‐dure of homogenation ,vacuum packing and irradiation .The homogeneity and stability of samples were de‐tected by ultra‐performance liquid chromatography‐tandem mass spectrometry (UPLC‐MS/MS) .The con‐centration of the chemical constituent of the sample was certified through the collaborative analysis pro‐gram participated by 8 laboratories ,and the uncertainty assessment was performed with property value of 2 .82 μg/kg ,and the expanded uncertainty of 0 .39 μg/kg (k= 2) .It is concluded that the preparation method for matrix reference materials for the dye residues provides one kind of reference .
